0.26.0

Breaking Changes

• The EnumVariantNames macro has been renamed VariantNames. The deprecation warning should steer you in the right direction for fixing the warning.
• The Iterator struct generated by EnumIter now has new bounds on it. This shouldn't break code unless you manually added the implementation in your code.
• Display now supports format strings using named fields in the enum variant. This should be a no-op for most code. However, if you were outputting a string like "Hello {field}", this will now be interpretted as a format string.
• EnumDiscriminant now inherits the repr and discriminant values from your main enum. This makes the discriminant type closer to a mirror of the original and that's always the goal.

New features

• The VariantArray macro has been added. This macro adds an associated constant VARIANTS to your enum. The constant is a &'static [Self] slice so that you can access all the variants of your enum. This only works on enums that only have unit variants.

  use strum::VariantArray;
  #[derive(Debug, VariantArray)]
  enum Color {
  Red,
  Blue,
  Green,
  }
  fn main() {
  println!("{:?}", Color::VARIANTS); // prints: ["Red", "Blue", "Green"]
  }
  

• The EnumTable macro has been experimentally added. This macro adds a new type that stores an item for each variant of the enum. This is useful for storing a value for each variant of an enum. This is an experimental feature because I'm not convinced the current api surface area is correct.

  use strum::EnumTable;
  #[derive(Copy, Clone, Debug, EnumTable)]
  enum Color {
  Red,
  Blue,
  Green,
  }
