[docs-rs]: https://img.shields.io/badge/docs.rs-66c2a5?style=for-the-badge&labelColor=555555&logo=docs.rs -//! -//! <br> -//! -//! This library provides a convenient derive macro for the standard library's -//! [`std::error::Error`] trait. -//! -//! <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 core::i32; -//! # use thiserror::Error; -//! # -//! #[derive(Error, Debug)] -//! pub enum Error { -//! #[error("invalid rdo_lookahead_frames {0} (expected < {max})", max = 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 that contains a `#[from]` -//! attribute. -//! -//! The variant using `#[from]` must not contain any other fields beyond the -//! source error (and possibly a backtrace — see below). Usually -//! `#[from]` fields are unnamed, but `#[from]` is allowed on a named field -//! too. -//! -//! ```rust -//! # use core::fmt::{self, Display}; -//! # use std::io; -//! # use thiserror::Error; -//! # -//! # mod globset { -//! # #[derive(thiserror::Error, Debug)] -//! # #[error("...")] -//! # pub struct Error; -//! # } -//! # -//! #[derive(Error, Debug)] -//! pub enum MyError { -//! Io(#[from] io::Error), -//! Glob(#[from] globset::Error), -//! } -//! # -//! # impl Display for MyError { -//! # fn fmt(&self, formatter: &mut fmt::Formatter) -> fmt::Result { -//! # unimplemented!() -//! # } -//! # } -//! ``` -//! -//! - 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 core::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`. Using `Backtrace` in errors requires a -//! nightly compiler with Rust version 1.73 or newer. -//! -//! ```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. The `#[backtrace]` -//! attribute requires a nightly compiler with Rust version 1.73 or newer. -//! -//! ```rust -//! # const IGNORE: &str = stringify! { -//! #[derive(Error, Debug)] -//! pub enum MyError { -//! Io { -//! #[backtrace] -//! source: io::Error, -//! }, -//! } -//! # }; -//! ``` -//! -//! - For variants that use `#[from]` and also contain a `Backtrace` field, a -//! backtrace is captured from within the `From` impl. -//! -//! ```rust -//! # const IGNORE: &str = stringify! { -//! #[derive(Error, Debug)] -//! pub enum MyError { -//! Io { -//! #[from] -//! source: io::Error, -//! backtrace: Backtrace, -//! }, -//! } -//! # }; -//! ``` -//! -//! - 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. -//! -//!
