chore(deps): bump thiserror from 1.0.68 to 2.0.1

[dependabot[bot]]

Bumps thiserror from 1.0.68 to 2.0.1.

Release notes

Sourced from thiserror's releases.

2.0.1

• Support errors that contain a dynamically sized final field (#375)
• Improve inference of trait bounds for fields that are interpolated multiple times in an error message (#377)

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)]
