Traits

The enumcapsulate crate exports the following traits:

Traits	Functionality
AsVariant	Umbrella derive macro for AsVariantRef, and AsVariantMut
AsVariantMut	Used to do a cheap mutable-to-mutable reference conversion between an outer enum's and its inner variant's type
AsVariantRef	Used to do a cheap reference-to-reference reference conversion between an outer enum's and its inner variant's type
Encapsulate	Umbrella derive macro for AsVariantMut, AsVariantRef, From, FromVariant, IntoVariant, IsVariant, TryInto, VariantDiscriminant, and VariantDowncast AsVariantMut
FromVariant	Used to do variant-to-enum conversions between an outer enum's and its inner variant's type
IntoVariant	Used to do enum-to-variant conversions between an outer enum's and its inner variant's type
IsVariant	Used to check type of an enum's inner variant's type
VariantDiscriminant	Used to obtain an enum variant's discriminant
VariantDowncast	Convenience umbrella trait utilizing AsVariantRef, AsVariantMut, and IntoVariant
