Changelog

Sourced from strum_macros's changelog.

Changelog

0.20.0

• Breaking Change: EnumVariantNames now properly adjusts to the to_string and serialize attributes.

0.19.0

• Fixed a regression using nth_back. #85

• Added repository to Cargo.toml. #90

• Correctly handle fill align in Display impls. #95

• Breaking Change: Use Associated Constant for EnumCount instead of const fn and free constant. #99 This behavior is consistent with the other derives.

• Breaking Change. default and disabled should now be written as markers instead of key value pairs. Here is the old way of adding these attributes to a variant.

  // OLD WAY
  enum Test {
    #[strum(disabled = "true", default = "true")]
    Variant(String)
  }
  

  Here is the new way. There is less ambiguity in the new syntax.

  enum Test {
    #[strum(disabled, default)]
    Variant(String)
  }
  

• Breaking Change. Most of the strum plugins will now error more aggresively on invalid options being used. Historically, the plugins have ignore invalid options, but most of these should error now. Silent errors are a rust anti-pattern.

0.18.0

• Only copy across "doc", "cfg", "allow", "deny" attributes from main enum variants to discriminant variants. #73
• The formatting of generated serialization variants returned by get_serializations() from an enum that derives EnumMessage is now affected by the serialize_all property on the enum. #84
• IntoEnumIterator now has the constraint IntoEnumIterator::Iterator<Item=Self> and Self: Sized. This makes it much easier to be generic over IntoEnumIterator and enum variants must be sized. #80

0.17.1

• Fixed an issue caused by combining #60 and #76

0.17.0
