[dependabot]

Bumps strum_macros from 0.27.2 to 0.28.0.

Changelog

Sourced from strum_macros's changelog.

0.28.0

• #461: Allow any kind of passthrough attributes on EnumDiscriminants.

  • Previously only list-style attributes (e.g. #[strum_discriminants(derive(...))]) were supported. Now path-only (e.g. #[strum_discriminants(non_exhaustive)]) and name/value (e.g. #[strum_discriminants(doc = "foo")]) attributes are also supported.

• #462: Add missing #[automatically_derived] to generated impls not covered by #444.

• #466: Bump MSRV to 1.71, required to keep up with updated syn and windows-sys dependencies. This is a breaking change if you're on an old version of rust.

• #469: Use absolute paths in generated proc macro code to avoid potential name conflicts.

• #465: Upgrade phf dependency to v0.13.

• #473: Fix cargo fmt / clippy issues and add GitHub Actions CI.

• #477: strum::ParseError now implements core::fmt::Display instead std::fmt::Display to make it #[no_std] compatible. Note the Error trait wasn't available in core until 1.81 so strum::ParseError still only implements that in std.

• #476: Breaking Change - EnumString now implements From<&str> (infallible) instead of TryFrom<&str> when the enum has a #[strum(default)] variant. This more accurately reflects that parsing cannot fail in that case. If you need the old TryFrom behavior, you can opt back in using parse_error_ty and parse_error_fn:

  #[derive(EnumString)]
  #[strum(parse_error_ty = strum::ParseError, parse_error_fn = make_error)]
  pub enum Color {
      Red,
      #[strum(default)]
      Other(String),
  }
  fn make_error(x: &str) -> strum::ParseError {
  strum::ParseError::VariantNotFound
  }

• #431: Fix bug where EnumString ignored the parse_err_ty attribute when the enum had a #[strum(default)] variant.

• #474: EnumDiscriminants will now copy default over from the original enum to the Discriminant enum.

  #[derive(Debug, Default, EnumDiscriminants)]
  #[strum_discriminants(derive(Default))] // <- Remove this in 0.28.
  enum MyEnum {
      #[default] // <- Will be the #[default] on the MyEnumDiscriminant
      #[strum_discriminants(default)] // <- Remove this in 0.28
      Variant0,
      Variant1 { a: NonDefault },
  }
