Struct syn::Variant

pub struct Variant {
    pub attrs: Vec<Attribute>,
    pub ident: Ident,
    pub fields: Fields,
    pub discriminant: Option<(Eq, Expr)>,
}

An enum variant.

This type is available only if Syn is built with the "derive" or "full" feature.

Fields

attrs: Vec<Attribute>

Attributes tagged on the variant.

ident: Ident

Name of the variant.

fields: Fields

Content stored in the variant.

discriminant: Option<(Eq, Expr)>

Explicit discriminant: Variant = 1

Trait Implementations

impl Clone for Variant

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Variant

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Variant

fn hash<H>(&self, state: &mut H)where
    H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Parse for Variant

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

impl PartialEq<Variant> for Variant

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToTokens for Variant

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) -> TokenStreamwhere
    Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for Variant
