Enum VariantKind 

#[non_exhaustive]
pub enum VariantKind {
    Unit,
    Newtype,
    Tuple,
    Struct,
}

The kind of an enum variant.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unit

A variant without content (A).

Newtype

A variant with a single unnamed field (A(T)).

Tuple

A variant with multiple unnamed fields (A(T, U)).

Struct

A variant with named fields (A { x: T }).
