Struct EnumData

Source
pub struct EnumData { /* private fields */ }
Expand description

A structure to make trait implementation to enums more efficient.

Implementations§

Source§

impl EnumData

Source

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

Returns an iterator over field types.

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

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

Returns an iterator over variant names.

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