TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,

|
||||
|
||||
This library provides [`anyhow::Error`][Error], a trait object based error type
|
||||
for easy idiomatic error handling in Rust applications.
|
||||
|
||||
[Error]: https://docs.rs/anyhow/1.0/anyhow/struct.Error.html
|
||||
|
||||
```toml
|
||||
[dependencies]
|
||||
anyhow = "1.0"
|
||||
```
|
||||
|
||||
*Compiler support: requires rustc 1.39+*
|
||||
|
||||
<br>
|
||||
|
||||
## Details
|
||||
|
||||
- Use `Result<T, anyhow::Error>`, or equivalently `anyhow::Result<T>`, as the
|
||||
return type of any fallible function.
|
||||
|
||||
Within the function, use `?` to easily propagate any error that implements the
|
||||
[`std::error::Error`] trait.
|
||||
|
||||
```rust
|
||||
use anyhow::Result;
|
||||
|
||||
fn get_cluster_info() -> Result<ClusterMap> {
|
||||
let config = std::fs::read_to_string("cluster.json")?;
|
||||
let map: ClusterMap = serde_json::from_str(&config)?;
|
||||
Ok(map)
|
||||
}
|
||||
```
|
||||
|
||||
[`std::error::Error`]: https://doc.rust-lang.org/std/error/trait.Error.html
|
||||
|
||||
- Attach context to help the person troubleshooting the error understand where
|
||||
things went wrong. A low-level error like "No such file or directory" can be
|
||||
annoying to debug without more context about what higher level step the
|
||||
application was in the middle of.
|
||||
|
||||
```rust
|
||||
use anyhow::{Context, Result};
|
||||
|
||||
fn main() -> Result<()> {
|
||||
...
|
||||
it.detach().context("Failed to detach the important thing")?;
|
||||
|
||||
let content = std::fs::read(path)
|
||||
.with_context(|| format!("Failed to read instrs from {}", path))?;
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
```console
|
||||
Error: Failed to read instrs from ./path/to/instrs.json
|
||||
|
||||
Caused by:
|
||||
No such file or directory (os error 2)
|
||||
```
|
||||
|
||||
- Downcasting is supported and can be by value, by shared reference, or by
|
||||
mutable reference as needed.
|
||||
|
||||
```rust
|
||||
// If the error was caused by redaction, then return a
|
||||
// tombstone instead of the content.
|
||||
match root_cause.downcast_ref::<DataStoreError>() {
|
||||
Some(DataStoreError::Censored(_)) => Ok(Poll::Ready(REDACTED_CONTENT)),
|
||||
None => Err(error),
|
||||
}
|
||||
```
|
||||
|
||||
- If using Rust ≥ 1.65, a backtrace is captured and printed with the error if
|
||||
the underlying error type does not already provide its own. In order to see
|
||||
backtraces, they must be enabled through the environment variables described
|
||||
in [`std::backtrace`]:
|
||||
|
||||
- If you want panics and errors to both have backtraces, set
|
||||
`RUST_BACKTRACE=1`;
|
||||
- If you want only errors to have backtraces, set `RUST_LIB_BACKTRACE=1`;
|
||||
- If you want only panics to have backtraces, set `RUST_BACKTRACE=1` and
|
||||
`RUST_LIB_BACKTRACE=0`.
|
||||
|
||||
[`std::backtrace`]: https://doc.rust-lang.org/std/backtrace/index.html#environment-variables
|
||||
|
||||
- Anyhow works with any error type that has an impl of `std::error::Error`,
|
||||
including ones defined in your crate. We do not bundle a `derive(Error)` macro
|
||||
but you can write the impls yourself or use a standalone macro like
|
||||
[thiserror].
|
||||
|
||||
```rust
|
||||
use thiserror::Error;
|
||||
|
||||
#[derive(Error, Debug)]
|
||||
pub enum FormatError {
|
||||
#[error("Invalid header (expected {expected:?}, got {found:?})")]
|
||||
InvalidHeader {
|
||||
expected: String,
|
||||
found: String,
|
||||
},
|
||||
#[error("Missing attribute: {0}")]
|
||||
MissingAttribute(String),
|
||||
}
|
||||
```
|
||||
|
||||
- One-off error messages can be constructed using the `anyhow!` macro, which
|
||||
supports string interpolation and produces an `anyhow::Error`.
|
||||
|
||||
```rust
|
||||
return Err(anyhow!("Missing attribute: {}", missing));
|
||||
```
|
||||
|
||||
A `bail!` macro is provided as a shorthand for the same early return.
|
||||
|
||||
```rust
|
||||
bail!("Missing attribute: {}", missing);
|
||||
```
|
||||
|
||||
<br>
|
||||
|
||||
## No-std support
|
||||
|
||||
In no_std mode, almost all of the same API is available and works the same way.
|
||||
To depend on Anyhow in no_std mode, disable our default enabled "std" feature in
|
||||
Cargo.toml. A global allocator is required.
|
||||
|
||||
```toml
|
||||
[dependencies]
|
||||
anyhow = { version = "1.0", default-features = false }
|
||||
```
|
||||
|
||||
With versions of Rust older than 1.81, no_std mode may require an additional
|
||||
`.map_err(Error::msg)` when working with a non-Anyhow error type inside a
|
||||
function that returns Anyhow's error type, as the trait that `?`-based error
|
||||
conversions are defined by is only available in std in those old versions.
|
||||
|
||||
<br>
|
||||
|
||||
## Comparison to failure
|
||||
|
||||
The `anyhow::Error` type works something like `failure::Error`, but unlike
|
||||
failure ours is built around the standard library's `std::error::Error` trait
|
||||
rather than a separate trait `failure::Fail`. The standard library has adopted
|
||||
the necessary improvements for this to be possible as part of [RFC 2504].
|
||||
|
||||
[RFC 2504]: https://github.com/rust-lang/rfcs/blob/master/text/2504-fix-error.md
|
||||
|
||||
<br>
|
||||
|
||||
## Comparison to thiserror
|
||||
|
||||
Use Anyhow if you don't care what error type your functions return, you just
|
||||
want it to be easy. This is common in application code. Use [thiserror] if you
|
||||
are a library that wants to design your own dedicated error type(s) so that on
|
||||
failures the caller gets exactly the information that you choose.

// Tagged dispatch mechanism for resolving the behavior of `anyhow!($expr)`.

// and backtrace() if it has a std::error::Error impl, otherwise require nothing
|
||||
// more than Display and Debug.
|
||||
//
|
||||
// Expressed in terms of specialization, we want something like:
|
||||
//
|
||||
// trait AnyhowNew {
|
||||
// fn new(self) -> Error;
|
||||
// }
|
||||
//
|
||||
// impl<T> AnyhowNew for T
|
||||
// where
|

// T: Display + Debug + Send + Sync + 'static,
|
||||
// {
|
||||
// default fn new(self) -> Error {
|

// /* no std error impl */

// }

|

// /* use std error's source() and backtrace() */
|
||||
// }

||||
// }

// Since specialization is not stable yet, instead we rely on autoref behavior

|
||||
//!
|
||||
//! <br>
|
||||
//!
|
||||
//! This library provides [`anyhow::Error`][Error], a trait object based error
|
||||
//! type for easy idiomatic error handling in Rust applications.
|
||||
//!
|
||||
//! <br>
|
||||
//!
|
||||
//! # Details
|
||||
//!
|
||||
//! - Use `Result<T, anyhow::Error>`, or equivalently `anyhow::Result<T>`, as
|
||||
//! the return type of any fallible function.
|
||||
//!
|
||||
//! Within the function, use `?` to easily propagate any error that implements
|
||||
//! the [`std::error::Error`] trait.
|
||||
//!
|
||||
//! ```
|
||||
//! # pub trait Deserialize {}
|
||||
//! #
|
||||
//! # mod serde_json {
|
||||
//! # use super::Deserialize;
|
||||
//! # use std::io;
|
||||
//! #
|
||||
//! # pub fn from_str<T: Deserialize>(json: &str) -> io::Result<T> {
|
||||
//! # unimplemented!()
|
||||
//! # }
|
||||
//! # }
|
||||
//! #
|
||||
//! # struct ClusterMap;
|
||||
//! #
|
||||
//! # impl Deserialize for ClusterMap {}
|
||||
//! #
|
||||
//! use anyhow::Result;
|
||||
//!
|
||||
//! fn get_cluster_info() -> Result<ClusterMap> {
|
||||
//! let config = std::fs::read_to_string("cluster.json")?;
|
||||
//! let map: ClusterMap = serde_json::from_str(&config)?;
|
||||
//! Ok(map)
|
||||
//! }
|
||||
//! #
|
||||
//! # fn main() {}
|
||||
//! ```
|
||||
//!
|
||||
//! - Attach context to help the person troubleshooting the error understand
|
||||
//! where things went wrong. A low-level error like "No such file or
|
||||
//! directory" can be annoying to debug without more context about what higher
|
||||
//! level step the application was in the middle of.
|
||||
//!
|
||||
//! ```
|
||||
//! # struct It;
|
||||
//! #
|
||||
//! # impl It {
|
||||
//! # fn detach(&self) -> Result<()> {
|
||||
//! # unimplemented!()
|
||||
//! # }
|
||||
//! # }
|
||||
//! #
|
||||
//! use anyhow::{Context, Result};
|
||||
//!
|
||||
//! fn main() -> Result<()> {
|
||||
//! # return Ok(());
|
||||
//! #
|
||||
//! # const _: &str = stringify! {
|
||||
//! ...
|
||||
//! # };
|
||||
//! #
|
||||
//! # let it = It;
|
||||
//! # let path = "./path/to/instrs.json";
|
||||
//! #
|
||||
//! it.detach().context("Failed to detach the important thing")?;
|
||||
//!
|
||||
//! let content = std::fs::read(path)
|
||||
//! .with_context(|| format!("Failed to read instrs from {}", path))?;
|
||||
//! #
|
||||
//! # const _: &str = stringify! {
|
||||
//! ...
|
||||
//! # };
|
||||
//! #
|
||||
//! # Ok(())
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! ```console
|
||||
//! Error: Failed to read instrs from ./path/to/instrs.json
|
||||
//!
|
||||
//! Caused by:
|
||||
//! No such file or directory (os error 2)
|
||||
//! ```
|
||||
//!
|
||||
//! - Downcasting is supported and can be by value, by shared reference, or by
|
||||
//! mutable reference as needed.
|
||||
//!
|
||||
//! ```
|
||||
//! # use anyhow::anyhow;
|
||||
//! # use std::fmt::{self, Display};
|
||||
//! # use std::task::Poll;
|
||||
//! #
|
||||
//! # #[derive(Debug)]
|
||||
//! # enum DataStoreError {
|
||||
//! # Censored(()),
|
||||
//! # }
|
||||
//! #
|
||||
//! # impl Display for DataStoreError {
|
||||
//! # fn fmt(&self, formatter: &mut fmt::Formatter) -> fmt::Result {
|
||||
//! # unimplemented!()
|
||||
//! # }
|
||||
//! # }
|
||||
//! #
|
||||
//! # impl std::error::Error for DataStoreError {}
|
||||
//! #
|
||||
//! # const REDACTED_CONTENT: () = ();
|
||||
//! #
|
||||
//! # let error = anyhow!("...");
|
||||
//! # let root_cause = &error;
|
||||
//! #
|
||||
//! # let ret =
|
||||
//! // If the error was caused by redaction, then return a
|
||||
//! // tombstone instead of the content.
|
||||
//! match root_cause.downcast_ref::<DataStoreError>() {
|
||||
//! Some(DataStoreError::Censored(_)) => Ok(Poll::Ready(REDACTED_CONTENT)),
|
||||
//! None => Err(error),
|
||||
//! }
|
||||
//! # ;
|
||||
//! ```
|
||||
//!
|
||||
//! - If using Rust ≥ 1.65, a backtrace is captured and printed with the
|
||||
//! error if the underlying error type does not already provide its own. In
|
||||
//! order to see backtraces, they must be enabled through the environment
|
||||
//! variables described in [`std::backtrace`]:
|
||||
//!
|
||||
//! - If you want panics and errors to both have backtraces, set
|
||||
//! `RUST_BACKTRACE=1`;
|
||||
//! - If you want only errors to have backtraces, set `RUST_LIB_BACKTRACE=1`;
|
||||
//! - If you want only panics to have backtraces, set `RUST_BACKTRACE=1` and
|
||||
//! `RUST_LIB_BACKTRACE=0`.
|
||||
//!
|
||||
//! [`std::backtrace`]: https://doc.rust-lang.org/std/backtrace/index.html#environment-variables
|
||||
//!
|
||||
//! - Anyhow works with any error type that has an impl of `std::error::Error`,
|
||||
//! including ones defined in your crate. We do not bundle a `derive(Error)`
|
||||
//! macro but you can write the impls yourself or use a standalone macro like
|
||||
//! [thiserror].
|
||||
//!
|
||||
//! [thiserror]: https://github.com/dtolnay/thiserror
|
||||
//!
|
||||
//! ```
|
||||
//! use thiserror::Error;
|
||||
//!
|
||||
//! #[derive(Error, Debug)]
|
||||
//! pub enum FormatError {
|
||||
//! #[error("Invalid header (expected {expected:?}, got {found:?})")]
|
||||
//! InvalidHeader {
|
||||
//! expected: String,
|
||||
//! found: String,
|
||||
//! },
|
||||
//! #[error("Missing attribute: {0}")]
|
||||
//! MissingAttribute(String),
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//! - One-off error messages can be constructed using the `anyhow!` macro, which
|
||||
//! supports string interpolation and produces an `anyhow::Error`.
|
||||
//!
|
||||
//! ```
|
||||
//! # use anyhow::{anyhow, Result};
|
||||
//! #
|
||||
//! # fn demo() -> Result<()> {
|
||||
//! # let missing = "...";
|
||||
//! return Err(anyhow!("Missing attribute: {}", missing));
|
||||
//! # Ok(())
|
||||
//! # }
|
||||
//! ```
|
||||
//!
|
||||
//! A `bail!` macro is provided as a shorthand for the same early return.
|
||||
//!
|
||||
//! ```
|
||||
//! # use anyhow::{bail, Result};
|
||||
//! #
|
||||
//! # fn demo() -> Result<()> {
|
||||
//! # let missing = "...";
|
||||
//! bail!("Missing attribute: {}", missing);
|
||||
//! # Ok(())
|
||||
//! # }
|
||||
//! ```
|
||||
//!
|
||||
//! <br>
|
||||
//!
|
||||
//! # No-std support
|
||||
//!
|
||||
//! In no_std mode, almost all of the same API is available and works the same
|
||||
//! way. To depend on Anyhow in no_std mode, disable our default enabled "std"
|
||||
//! feature in Cargo.toml. A global allocator is required.
|
||||
//!
|
||||
//! ```toml
|
||||
//! [dependencies]
|
||||
//! anyhow = { version = "1.0", default-features = false }
|
||||
//! ```
|
||||
//!
|
||||
//! With versions of Rust older than 1.81, no_std mode may require an additional
|
||||
//! `.map_err(Error::msg)` when working with a non-Anyhow error type inside a
|
||||
//! function that returns Anyhow's error type, as the trait that `?`-based error
|
||||
//! conversions are defined by is only available in std in those old versions.
