Traits

The enumcapsulate crate exports the following traits:

Traits	Functionality
Encapsulate	Umbrella derive macro for AsVariant, AsVariantMut, AsVariantRef, From, FromVariant, IntoVariant, TryInto, and VariantDowncast.
FromVariant	Creates an instance of Self from the unambiguous field type of one of its variants.
IntoVariant	Returns the current variant's field, consuming self.
AsVariant	Provides owned access to the current variant's field.
AsVariantMut	Provides mutable borrowed access to the current variant's field.
AsVariantRef	Provides borrowed access to the current variant's field.
VariantDowncast	Convenience umbrella trait utilizing AsVariant, AsVariantRef, AsVariantMut, and IntoVariant.
VariantDiscriminant	Used to obtain an enum variant's discriminant.
