Struct derive_utils::EnumData[−][src]

pub struct EnumData { /* fields omitted */ }
[−]

A structure to make trait implementation to enums more efficient.

Implementations

impl EnumData[src][−]

pub fn field_types(&self) -> impl ExactSizeIterator<Item = &Type> + Clone[src][−]

Returns an iterator over field types.

enum Enum<TypeA, TypeB> {
    VariantA(TypeA),
             ^^^^^
    VariantB(TypeB),
             ^^^^^
}

pub fn variant_idents(&self) -> impl ExactSizeIterator<Item = &Ident> + Clone[src][−]

Returns an iterator over variant names.

enum Enum<TypeA, TypeB> {
    VariantA(TypeA),
    ^^^^^^^^
    VariantB(TypeB),
    ^^^^^^^^
}
