Improve parsing of `.0` and `.var`-style format arguments ([#​54](https://togithub.com/dtolnay/thiserror/issues/54)) For example the one here as the argument to the `match` expression would now be recognized correctly: ```rust #[derive(Error, Debug)] pub enum MyError { #[error("{}: {0}", match .1 { Some(n) => format!("a variant error occurred with n={}", n), None => format!("there was an empty variant error"), })] Variant(String, Option), } ``` ### [`v1.0.9`](https://togithub.com/dtolnay/thiserror/releases/tag/1.0.9) [Compare Source](https://togithub.com/dtolnay/thiserror/compare/1.0.8...1.0.9) -

Add #\[error(transparent)] attribute for delegating Error impl to one field ([#​50](https://togithub.com/dtolnay/thiserror/issues/50)) This is useful for hiding error variants from a library's public error type: ```rust #[derive(Error, Debug)] #[error(transparent)] // source and Display delegate to ErrorKind pub struct Error(ErrorKind); #[derive(Error, Debug)] /*private*/ enum ErrorKind { #[error("...")] E0, #[error("...")] E1(#[source] io::Error), } ``` And also for enums that need an "anything else" variant; such variants tend not to have their own Display message but just forward through to the underlying error's Display and source: ```rust #[derive(Error, Debug)] pub enum MyError { ... #[error(transparent)] Other(#[from] anyhow::Error), // source and Display delegate to anyhow::Error } ``` ### [`v1.0.6`](https://togithub.com/dtolnay/thiserror/releases/tag/1.0.6) [Compare Source](https://togithub.com/dtolnay/thiserror/compare/1.0.5...1.0.6) -

Support interpolating `Path` and `PathBuf` fields as if they had a Display impl ```rust use std::io; use std::path::PathBuf; use thiserror::Error; #[derive(Error, Debug)] pub enum Error { #[error("failed to load {1}")] Read(#[source] io::Error, PathBuf), } ``` In previous releases this would fail to compile with: ```console error[E0277]: `std::path::PathBuf` doesn't implement `std::fmt::Display` --> src/main.rs:7:13 | 7 | #[error("failed to load {1}")] | ^^^^^^^^^^^^^^^^^^^^ `std::path::PathBuf` cannot be formatted with the default formatter ``` ### [`v1.0.4`](https://togithub.com/dtolnay/thiserror/releases/tag/1.0.4) [Compare Source](https://togithub.com/dtolnay/thiserror/compare/1.0.3...1.0.4) -

Fix `#[error("{v0}")]` where an interpolated identifier contains number digits ([#​34](https://togithub.com/dtolnay/thiserror/issues/34)) ### [`v1.0.2`](https://togithub.com/dtolnay/thiserror/releases/tag/1.0.2) [Compare Source](https://togithub.com/dtolnay/thiserror/compare/1.0.1...1.0.2) - Add a `#[from]` attribute to request an implementation of `std::convert::From` from your error's source error types, making it easy to build your error via the `?` operator. ```rust use thiserror::Error; #[derive(Error, Debug)] pub enum Error { Io(#[from] io::Error), Json(#[from] serde_json::Error), Regex(#[from] regex::Error), Other(#[from] anyhow::Error), } ``` We only permit `From` to be derived from the error's source field, not any arbitrary other field. Notice that this allows `#[from]` to imply `#[source]` so you don't need to also specify `#[source]` explicitly. 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 #[derive(Error, Debug)] pub enum MyError { Io { #[from] source: io::Error, backtrace: Backtrace, }, } ``` - Named fields with the name `source` are assumed to be the error source and so no longer require an explicit `#[source]` attribute. - Enum variants now inherit the `#[error(...)]` attribute from atop the enum if there is one. ```rust use thiserror::Error; #[derive(Error, Debug)] #[error("{0}")] // applies to every variant without its own attr pub enum Error { Io(io::Error), Json(serde_json::Error), Regex(regex::Error), #[error("unknown error")] Unknown, } ``` ### [`v1.0.1`](https://togithub.com/dtolnay/thiserror/releases/tag/1.0.1) [Compare Source](https://togithub.com/dtolnay/thiserror/compare/1.0.0...1.0.1) - Documentation improvements
