Struct derive_utils::EnumData

pub struct EnumData { /* private fields */ }

A structure to make trait implementation to enums more efficient.

Implementations

impl EnumData

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

Returns an iterator over field types.

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

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

Returns an iterator over variant names.

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

Trait Implementations

impl Deref for EnumData

type Target = ItemEnum

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<EnumData> for ItemEnum

fn from(other: EnumData) -> Self

Performs the conversion.

impl Parse for EnumData

fn parse(input: ParseStream<'_>) -> Result<Self>

impl ToTokens for EnumData

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.
