Generate `#[automatically_derived]`

Fixed

• Apply #[automatically_derived] to all generated implementations.

Fix `Copy + Clone` implementation

Fixed

• Use the Copy implementation for Clone only if no bounds are present.

Make discriminant default type validation edition-proof

Changed

• Use safe casting in PartialOrd and Ord implementations in more cases when
  possible.
• Avoid unnecessarily validating the default discriminant type in some cases.
• Apply default enum discriminant type validation to all representations and
  make it cross-edition safe.

Take representation into account when getting discriminant

Fixed

• Take representation into account when determining the discriminant type.

Changed

• Use stable methods to retrieve the discriminant in PartialOrd and Ord
  implementations. Safe methods used with the safe crate feature don't use
  recursive matches anymore, significantly improving the performance.

Fix `PartialOrd` implementation using `Ord` with bounds [YANKED]

Fixed

• Don't use Ord in PartialOrd implementations if using any bounds.

Fix field name collisions [YANKED]

Fixed

• Avoid collisions between field names and trait method parameters.

Changed

• PartialOrd implementations now use Ord if applicable.

Fix Raw Identifiers [YANKED]

Fixed

• Correctly handle raw identifiers in named fields.

`syn` v2.0 update [YANKED]

Changed

• Updated syn to v2.
• Debug output of structs that skip fields appears non_exhaustive now.

Deprecated

• The crate attribute now takes a bare path instead of a path inside a string
  literal.

Added `incomparable` attribute for partial comparison traits [YANKED]

Added

• incomparable variant and item attribute for PartialEq and PartialOrd
  derives, yielding false on all comparisons but !=.

1.0 version release! 🥳 [YANKED]

• No changes.
