[0.6.3] - 2025-05-22

Added

• Added support for variants with non-'static lifetimes for the VariantDiscriminant derive macro.

[0.6.2] - 2025-01-03

Changed

• Re-introduced type argument (nested = <Type>) of #[enumcapsulate(discriminant(nested))] variant attribute, but as an optional argument (required for fields using the parent enum's generic parameters).

[0.6.1] - 2025-01-02

Changed

• Changed the #[enumcapsulate(discriminant(nested))] variant attribute into a value-less unit attribute (nested), removing the previously required explicit type argument (nested = <Type>).

[0.6.0] - 2024-12-31

Added

• Added support for nested variant discriminants via variant-level #[enumcapsulate(discriminant(nested = …))] helper attribute for VariantDiscriminant derive macro, allowing for specifying a type of the sub-discriminant for the generated variant.

[0.5.0] - 2024-12-01

Added

• Added enum-level #[enumcapsulate(discriminant(…))] helper attribute for VariantDiscriminant derive macro, allowing for customizing repr = … and name = … for the generated enum.
• Added variant-level #[enumcapsulate(discriminant(…))] helper attribute for VariantDiscriminant derive macro, allowing for customizing value = … and name = … for the generated variant.
• Made enum generated by VariantDiscriminant derive macro implement Ord + PartialOrd.

Changed

• Bumped MSRV from "1.74.0" to "1.78.0".
• Made the enum-level #[enumcapsulate(exclude(…))] helper macros only have an effect on derives, when orchestrated through the Encapsulate derive macro.
• Made Encapsulate derive macro no longer derive VariantDiscriminant.
• Removed potentially confusing #[enumcapsulate(include(…))] helper attributes.
• Merged #[enumcapsulate(field(index = …))] and #[enumcapsulate(field(name = "…"))] into a single polymorph #[enumcapsulate(field = …)]
• Made enum generated by VariantDiscriminant derive macro have the same level of visibility as its source item.

[0.4.0] - 2024-11-18

Added

• Added dedicated trait AsVariant<T> for AsVariantRef<T>'s removed fn as_variant(&self) -> Option<T>.
• Added dedicated AsVariant derive macro for trait AsVariant<T>.
• Added enum-level #[enumcapsulate(exclude)]/#[enumcapsulate(exclude(…))] helper attribute.
• Added optional selection list to variant-level #[enumcapsulate(exclude(…))] helper attribute.
• Added optional selection list to variant-level #[enumcapsulate(include(…))] helper attribute.
• Added derive support for generic enums (by force-excluding variants that use generic const/type parameters).

Changed

• Removed enumcapsulate::macros and its redundant enumcapsulate::derive module in favor of re-exporting its items directly from crate::*, thus eliminating the need for individually importing trait + derive macro pairs:
  • Before: use enumcapsulate::{derive::FromVariant, FromVariant};
  • After: use enumcapsulate::FromVariant;
• Made Encapsulate derive macro derive also derive AsVariant<T>.
• Promoted field value of include(field = …) to its own top-level variant attribute with name/index variants:
  • #[enumcapsulate(field(index = …))]
  • #[enumcapsulate(field(name = "…"))]

Removed

• Removed fn as_variant(&self) -> Option<T> default trait method from AsVariantRef<T> (see Added section for more info).
• Removed IsVariant<T> trait and corresponding IsVariant derive macro.

[0.3.0] - 2024-05-24

Added

• Added #[enumcapsulate(exclude)] derive macro helper attribute for exclude specific variants from getting derives.

Changed

• Made derive macros more lenient by ignoring inapplicable variants (i.e. with fewer or more than one field), rather than bailing out.

[0.2.2] - 2024-05-23

Changed

• Updated dependencies:
  • enumcapsulate-macros from 0.1.0 to 0.2.1
• The VariantDiscriminant derive macro now also supports enums with arbitrary variant shapes.

[0.2.1] - 2024-05-05

Changed

• Updated dependencies:
  • proc-macro2 from 1.0.79 to 1.0.81
  • quote from 1.0.35 to 1.0.36
  • syn from 2.0.53 to 2.0.60

[0.2.0] - 2024-03-21

Changed

• Updated dependencies:
  • proc-macro2 from 1.0.76 to 1.0.79
  • syn from 2.0.48 to 2.0.53
• Bumped MSRV from 1.70.0 to 1.74.0

[0.1.0] - TBD

Initial release.
