Release Notes

Peternator7/strum (strum)

v0.25.0

Breaking Changes

• #​261 Upgrade syn dependency to version 2. This bumps the msrv to
  1.56. It's impractical to maintain a package where a core dependency of the ecosystem has a different msrv than this one.

• 270 Change the to_string behavior when using default. Now, when
  using default, the display method will return the display version of the value contained in the enum rather than
  the name of the variant.

  #[derive(strum::Display)]
  enum Color {
    Red,
    Blue,
    Green,
    #[strum(default)]
    Other(String)
  }
  
  fn main() {
    // This used to print "Other", now it prints "Purple"
    assert_eq!(Color::Other("Purple".to_string()).to_string(), "Purple");
  }

  If you want the old behavior, you can use the to_string attribute to override this behavior. See the PR for an example.

• 268 Update the behavior of EnumCount to exclude variants that are
  disabled. This is a breaking change, but the behavior makes it more consistent with other methods.

New Features

• #​257 This PR adds the EnumIs macro that automatically implements
  is_{variant_name} methods for each variant.

  #[derive(EnumIs)]
  enum Color {
      Red,
      Blue,
      Green,
  }
  
  #[test]
  fn simple_test() {
      assert!(Color::Red.is_red());
  }

v0.24.1

• #​220. Add support for PHF in EnumString (opt-in runtime
  performance improvements for large enums as #[strum(use_phf)], requires phf feature and increases MSRV to 1.46)
  • #​224 tweaked the algorithm.
• #​217: Automatically implement TryFrom in FromRepr. This is
  technically a breaking change, but the fix is to just remove the manual implementation of TryFrom so it shouldn't
  be more than a minor inconvenience.
