Release Notes

Peternator7/strum (strum)

v0.28.0

Compare Source

• #​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 },
  }

v0.27.2

Compare Source

• #​141: Adding support for doc comments on EnumDiscriminants generated type.

  • The doc comment will be copied from the variant on the type itself.

• #​435:allow discriminants on empty enum.

• #​443: Change enum table callbacks to FnMut.

• #​444: Add #[automatically_derived] to the impls by @​dandedotdev in #​444

  • This should make the linter less noisy with warnings in generated code.

• #​440: Implement a suffix attribute for serialization of enum variants.

  #[derive(strum::Display)]
  #[strum(suffix=".json")]
  #[strum(serialize_all="snake_case")]
  enum StorageConfiguration {
    PostgresProvider,
    S3StorageProvider,
    AzureStorageProvider,
  }
  
  fn main() {
    let response = SurveyResponse::Other("It was good".into());
    println!("Loading configuration from: {}", StorageConfiguration::PostgresProvider);
    // prints: Loaded Configuration from: postgres_provider.json
  }

• #​446: Drop needless rustversion dependency.

v0.27.1

Compare Source

• #​414: Fix docrs build error.

• #​417: Mention parse_error_ty and parse_error_fn that had been
  left out of the docs accidentally.

• #​421#​331: Implement
  #[strum(transparent)] attribute on IntoStaticStr, Display and AsRefStr that forwards the implmenentation to
  the inner value. Note that for static strings, the inner value must be convertible to an &'static str.

  #[derive(strum::Display)]
  enum SurveyResponse {
    Yes,
    No,
    #[strum(transparent)]
    Other(String)
  }
  
  fn main() {
    let response = SurveyResponse::Other("It was good".into());
    println!("Question: Did you have fun?");
    println!("Answer: {}", response);
    // prints: Answer: It was good
  }

Highlights

• #​407: Display is now correctly derived in [no_std] projects.
• #​402: EnumIter now implements Send + Sync
• #​400: EnumTryAs now handles attributes on variant fields correctly.
• #​398: strum is now on rust 2021
• #​391: EnumProperties correctly implements get_bool and get_int
  finally. 🎉
• #​380: FromString now supports 2 additional attributes, parse_error_ty
  and parse_error_fn that can be added to use a custom error type rather than the default strum error message.
  • #​410: These attributes accept a Path rather than a String
    to improve behavior with rust-analyzer.

Breaking Changes

• #​384: MSRV is now 1.66.1
• #​391: EnumProperties doesn't provide default implementations anymore.
  This would have required you to manually implement this trait which should be very uncommon.
