This library provides a convenient derive macro for the standard library's +//! [`std::error::Error`] trait. +//! +//! [`std::error::Error`]: https://doc.rust-lang.org/std/error/trait.Error.html +//! +//! <br> +//! +//! # Example +//! +//! ```rust +//! # use std::io; +//! use thiserror::Error; +//! +//! #[derive(Error, Debug)] +//! pub enum DataStoreError { +//! #[error("data store disconnected")] +//! Disconnect(#[from] io::Error), +//! #[error("the data for key `{0}` is not available")] +//! Redaction(String), +//! #[error("invalid header (expected {expected:?}, found {found:?})")] +//! InvalidHeader { +//! expected: String, +//! found: String, +//! }, +//! #[error("unknown data store error")] +//! Unknown, +//! } +//! ``` +//! +//! <br> +//! +//! # Details +//! +//! - Thiserror deliberately does not appear in your public API. You get the +//! same thing as if you had written an implementation of `std::error::Error` +//! by hand, and switching from handwritten impls to thiserror or vice versa +//! is not a breaking change. +//! +//! - Errors may be enums, structs with named fields, tuple structs, or unit +//! structs. +//! +//! - A `Display` impl is generated for your error if you provide +//! `#[error("...")]` messages on the struct or each variant of your enum, as +//! shown above in the example. +//! +//! The messages support a shorthand for interpolating fields from the error. +//! +//! - `#[error("{var}")]` ⟶ `write!("{}", self.var)` +//! - `#[error("{0}")]` ⟶ `write!("{}", self.0)` +//! - `#[error("{var:?}")]` ⟶ `write!("{:?}", self.var)` +//! - `#[error("{0:?}")]` ⟶ `write!("{:?}", self.0)` +//! +//! These shorthands can be used together with any additional format args, +//! which may be arbitrary expressions. For example: +//! +//! ```rust +//! # use std::i32; +//! # use thiserror::Error; +//! # +//! #[derive(Error, Debug)] +//! pub enum Error { +//! #[error("invalid rdo_lookahead_frames {0} (expected < {})", i32::MAX)] +//! InvalidLookahead(u32), +//! } +//! ``` +//! +//! If one of the additional expression arguments needs to refer to a field of +//! the struct or enum, then refer to named fields as `.var` and tuple fields +//! as `.0`. +//! +//! ```rust +//! # use thiserror::Error; +//! # +//! # fn first_char(s: &String) -> char { +//! # s.chars().next().unwrap() +//! # } +//! # +//! # #[derive(Debug)] +//! # struct Limits { +//! # lo: usize, +//! # hi: usize, +//! # } +//! # +//! #[derive(Error, Debug)] +//! pub enum Error { +//! #[error("first letter must be lowercase but was {:?}", first_char(.0))] +//! WrongCase(String), +//! #[error("invalid index {idx}, expected at least {} and at most {}", .limits.lo, .limits.hi)] +//! OutOfBounds { idx: usize, limits: Limits }, +//! } +//! ``` +//! +//! - A `From` impl is generated for each variant containing a `#[from]` +//! attribute. +//! +//! Note that the variant must not contain any other fields beyond the source +//! error and possibly a backtrace. A backtrace is captured from within the +//! `From` impl if there is a field for it. +//! +//! ```rust +//! # const IGNORE: &str = stringify! { +//! #[derive(Error, Debug)] +//! pub enum MyError { +//! Io { +//! #[from] +//! source: io::Error, +//! backtrace: Backtrace, +//! }, +//! } +//! # }; +//! ``` +//! +//! - The Error trait's `source()` method is implemented to return whichever +//! field has a `#[source]` attribute or is named `source`, if any. This is +//! for identifying the underlying lower level error that caused your error. +//! +//! The `#[from]` attribute always implies that the same field is `#[source]`, +//! so you don't ever need to specify both attributes. +//! +//! Any error type that implements `std::error::Error` or dereferences to `dyn +//! std::error::Error` will work as a source. +//! +//! ```rust +//! # use std::fmt::{self, Display}; +//! # use thiserror::Error; +//! # +//! #[derive(Error, Debug)] +//! pub struct MyError { +//! msg: String, +//! #[source] // optional if field name is `source` +//! source: anyhow::Error, +//! } +//! # +//! # impl Display for MyError { +//! # fn fmt(&self, formatter: &mut fmt::Formatter) -> fmt::Result { +//! # unimplemented!() +//! # } +//! # } +//! ``` +//! +//! - The Error trait's `provide()` method is implemented to provide whichever +//! field has a type named `Backtrace`, if any, as a +//! `std::backtrace::Backtrace`. +//! +//! ```rust +//! # const IGNORE: &str = stringify! { +//! use std::backtrace::Backtrace; +//! +//! #[derive(Error, Debug)] +//! pub struct MyError { +//! msg: String, +//! backtrace: Backtrace, // automatically detected +//! } +//! # }; +//! ``` +//! +//! - If a field is both a source (named `source`, or has `#[source]` or +//! `#[from]` attribute) *and* is marked `#[backtrace]`, then the Error +//! trait's `provide()` method is forwarded to the source's `provide` so that +//! both layers of the error share the same backtrace. +//! +//! ```rust +//! # const IGNORE: &str = stringify! { +//! #[derive(Error, Debug)] +//! pub enum MyError { +//! Io { +//! #[backtrace] +//! source: io::Error, +//! }, +//! } +//! # }; +//! ``` +//! +//! - Errors may use `error(transparent)` to forward the source and Display +//! methods straight through to an underlying error without adding an +//! additional message. This would be appropriate for enums that need an +//! "anything else" variant. +//! +//! ``` +//! # use thiserror::Error; +//! # +//! #[derive(Error, Debug)] +//! pub enum MyError { +//! # /* +//! ... +//! # */ +//! +//! #[error(transparent)] +//! Other(#[from] anyhow::Error), // source and Display delegate to anyhow::Error +//! } +//! ``` +//! +//! Another use case is hiding implementation details of an error +//! representation behind an opaque error type, so that the representation is +//! able to evolve without breaking the crate's public API. +//! +//! ``` +//! # use thiserror::Error; +//! # +//! // PublicError is public, but opaque and easy to keep compatible. +//! #[derive(Error, Debug)] +//! #[error(transparent)] +//! pub struct PublicError(#[from] ErrorRepr); +//! +//! impl PublicError { +//! // Accessors for anything we do want to expose publicly. +//! } +//! +//! // Private and free to change across minor version of the crate. +//! #[derive(Error, Debug)] +//! enum ErrorRepr { +//! # /* +//! ... +//! # */ +//! } +//! ``` +//! +//! - See also the [`anyhow`] library for a convenient single error type to use +//! in application code. +//! +//!
