Version 2.7.3

Other changes

Version 2.7.2

Other changes

  • Reduced RAM usage and improved compilation times when using derive(Enum) for large enums with overflow-checks enabled.

Version 2.7.1

Other changes

  • Updated author name.

Version 2.7.0

New features

  • Implemented EnumMap::from_fn.

Version 2.6.3

Other changes

  • Updated the repository URL as the project was migrated from GitHub to Codeberg.

  • This project is now compliant with the REUSE Specification.

Version 2.6.2

Other changes

  • Hide out_of_bounds reexport from documentation.

Version 2.6.1

Other changes

  • Provide better panic message when providing out-of-bounds index to `Enum::from_usize``.

Version 2.6.0

New features

  • EnumMap::as_array is now usable in const contexts.

Other changes

  • This crate now follows "N minus two" MSRV policy. This means that it supports the current Rust release, as well as the two before that.

  • Upgraded syn to 2.0.0.

Version 2.5.0

New features

  • Implemented EnumMap::as_array and EnumMap::as_mut_array (implemented by @Fuuzetsu).

  • Implemented PartialOrd and Ord for EnumMap (implemented by @nicarran).

Version 2.4.2

Other changes

  • Added license files to crate tarball.
  • Added changelog to crate tarball.

Version 2.4.1

Other changes

  • Improved performance of code generated for from_usize when deriving Enum.

Version 2.4.0

New features

  • Implemented Enum for () (unit type) and core::cmp::Ordering (implemented by @phimuemue).

  • Implemented EnumMap::into_array.

Version 2.3.0

New features

  • EnumMap::len is now usable in const contexts.

Other changes

  • Enum derive now can deal with re-definitions of usize and unimplemented.

Version 2.2.0

New features

  • EnumMap::from_array is now usable in const contexts.

Version 2.1.0

New features

  • Implemented DoubleEndedIterator for IntoIter.

  • Implemented EnumMap::into_values.

Other changes

  • Changed behavior of IntoIter so that it drops rest of the elements when one destructor panics.

Version 2.0.3

Other changes

  • Optimized performance of enum_map! macro.

Version 2.0.2

Other changes

  • Fixed safety problem when using enum_map! macro with enums that incorrectly implemented Enum trait.

Version 2.0.1

Other changes

  • Adjusted crate metadata to avoid lib.rs warnings.

Version 2.0.0

New features

  • Implemented FromIterator for EnumMap (implemented by @bit_network on GitLab).

  • Implemented EnumMap::map.

  • Derives support product types in addition to sum types (implemented by @bzim on GitLab).

  • It's now possible to access enum length by accessing LENGTH in Enum trait.

Breaking changes

  • Enum trait was split into two traits, Enum and EnumArray.

Version 1.1.1

Other changes

  • Worked around a bug in Clippy that caused false positives when using use_self lint for code that derived Enum trait.

Version 1.1.0

New features

  • Implemented Arbitrary for maps where the value type also implements Arbitrary. (You have to enable the "arbitrary" feature.)

Version 1.0.0

New features

  • It's now possible to use return and ? within macro_rules! macro.

  • Enum trait is much simpler having two methods only.

Other changes

  • Removed previously deprecated features.

  • Renamed to_usize to into_usize matching the naming convention used in Rust programming language.

Version 0.6.5

Other changes

  • Deprecated EnumMap::is_empty and EnumMap::new. EnumMap::new usages can be replaced with EnumMap::default.

Version 0.6.4

Other changes

  • Deprecated EnumMap::as_ptr and EnumMap::as_mut_ptr.

Version 0.6.3

New features

  • Iter and Values now implements Clone (added by @amanieu).

Version 0.6.2.

New features

  • Added EnumMap#clear method (added by @Riey, thanks :)).

Version 0.6.0

Incompatible changes

  • Now requires Rust 1.36.

Version 0.5.0

  • Fixed the issue where an aliasing From trait implementation caused compilation errors with enum_map! macro.

Incompatible changes

  • Now requires Rust 1.31.

Version 0.4.1

New features

  • Default serde features are disabled. This allows enabling serde feature when compiling without std.

Version 0.4.0

Change of #[derive(EnumMap)] to #[derive(Enum)] was supposed to appear in 0.3.0, but it was forgotten about. This release fixes just that.

Incompatible changes

  • Changed #[derive(EnumMap)] to #[derive(Enum)] to match trait name.

Version 0.3.1

  • Updated README use #[derive(EnumMap)] instead of #[derive(Enum)].

Version 0.3.0

New features

  • Implemented compact serde serialization for binary formats like bincode.

  • Iterator traits with exception now implement FusedIterator.

Incompatible changes

  • Increased required Rust version to 1.26.0.

  • Renamed Internal trait to Enum.

  • Added new associated constant POSSIBLE_VALUES to Enum trait, representing the number of possible values the type can have. Manual implementations are required to provide it.

  • Removed Enum implementation for Option<T>.

  • Implemented compact serialization, for formats like bincode. This makes it impossible to deserialize non-compact representation used by enum-map 0.2.0.

  • values method returns Values<V> as opposed to slice::Iter<V>.
