Updates the requirements on thiserror to permit the latest version.

Release notes

Sourced from thiserror's releases.

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} (#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.

    #[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 (#345)

    // 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 (#354)

    #[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 (#368, #369, #370, #372)

Features

  • Support disabling thiserror's standard library dependency by disabling the default "std" Cargo feature: thiserror = { version = "2", default-features = false } (#373)

  • Support using r#source as field name to opt out of a field named "source" being treated as an error's Error::source() (#350)

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