[Compare Source](https://github.com/dtolnay/thiserror/compare/1.0.69...2.0.0)

#### Breaking changes

-   Referencing keyword-named fields by a raw identifier like `{r#type}` inside a format string is no longer accepted; simply use the unraw name like `{type}` ([#&#8203;347](https://github.com/dtolnay/thiserror/issues/347))

    This aligns thiserror with the standard library's formatting macros, which gained support for implicit argument capture later than the release of this feature in thiserror 1.x.

    ```rust
    #[derive(Error, Debug)]
    #[error("... {type} ...")]  // Before: {r#type}
    pub struct Error {
        pub r#type: Type,
    }
    ```

-   Trait bounds are no longer inferred on fields whose value is shadowed by an explicit named argument in a format message ([#&#8203;345](https://github.com/dtolnay/thiserror/issues/345))

    ```rust
    // Before: impl<T: Octal> Display for Error<T>
    // After: impl<T> Display for Error<T>
    #[derive(Error, Debug)]
    #[error("{thing:o}", thing = "...")]
    pub struct Error<T> {
        thing: T,
    }
    ```

-   Tuple structs and tuple variants can no longer use numerical `{0}` `{1}` access at the same time as supplying extra positional arguments for a format message, as this makes it ambiguous whether the number refers to a tuple field vs a different positional arg ([#&#8203;354](https://github.com/dtolnay/thiserror/issues/354))

    ```rust
    #[derive(Error, Debug)]
    #[error("ambiguous: {0} {}", $N)]
    //                  ^^^ Not allowed, use #[error("... {0} {n}", n = $N)]
    pub struct TupleError(i32);
    ```

-   Code containing invocations of thiserror's `derive(Error)` must now have a direct dependency on the `thiserror` crate regardless of the error data structure's contents ([#&#8203;368](https://github.com/dtolnay/thiserror/issues/368), [#&#8203;369](https://github.com/dtolnay/thiserror/issues/369), [#&#8203;370](https://github.com/dtolnay/thiserror/issues/370), [#&#8203;372](https://github.com/dtolnay/thiserror/issues/372))

#### Features

-   Support disabling thiserror's standard library dependency by disabling the default "std" Cargo feature: `thiserror = { version = "2", default-features = false }` ([#&#8203;373](https://github.com/dtolnay/thiserror/issues/373))

-   Support using `r#source` as field name to opt out of a field named "source" being treated as an error's `Error::source()` ([#&#8203;350](https://github.com/dtolnay/thiserror/issues/350))

    ```rust
    #[derive(Error, Debug)]
    #[error("{source} ==> {destination}")]
    pub struct Error {
        r#source: char,
        destination: char,
    }

    let error = Error { source: 'S', destination: 'D' };
    ```

-   Infinite recursion in a generated Display impl now produces an `unconditional_recursion` warning ([#&#8203;359](https://github.com/dtolnay/thiserror/issues/359))

    ```rust
    #[derive(Error, Debug)]
    #[error("??? {self}")]
    pub struct Error;
    ```

-   A new attribute `#[error(fmt = path::to::myfmt)]` can be used to write formatting logic for an enum variant out-of-line ([#&#8203;367](https://github.com/dtolnay/thiserror/issues/367))

    ```rust
    #[derive(Error, Debug)]
    pub enum Error {
        #[error(fmt = demo_fmt)]
        Demo { code: u16, message: Option<String> },
    }

    fn demo_fmt(code: &u16, message: &Option<String>, formatter: &mut fmt::Formatter) -> fmt::Result {
        write!(formatter, "{code}")?;
        if let Some(msg) = message {
            write!(formatter, " - {msg}")?;
        }
        Ok(())
    }
    ```

-   Enums with an enum-level format message are now able to have individual variants that are `transparent` to supersede the enum-level message ([#&#8203;366](https://github.com/dtolnay/thiserror/issues/366))

    ```rust
    #[derive(Error, Debug)]
    #[error("my error {0}")]
    pub enum Error {
        Json(#[from] serde_json::Error),
        Yaml(#[from] serde_yaml::Error),
        #[error(transparent)]
        Other(#[from] anyhow::Error),
    }
    ```
