Struct syn::token::Underscore

pub struct Underscore {
    pub spans: [Span; 1],
}

_

Usage: wildcard patterns, inferred types, unnamed items in constants, extern crates, use declarations, and destructuring assignment.

Don’t try to remember the name of this type — use the Token! macro instead.

Fields

spans: [Span; 1]

Trait Implementations

impl Clone for Underscore

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 Underscore

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

Formats the value using the given formatter.

impl Default for Underscore

fn default() -> Self

Returns the “default value” for a type.

impl Deref for Underscore

type Target = WithSpan

The resulting type after dereferencing.

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

Dereferences the value.

impl DerefMut for Underscore

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<Underscore> for Ident

fn from(token: Underscore) -> Ident

Converts to this type from the input type.

impl Hash for Underscore

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

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 Underscore

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

impl PartialEq for Underscore

fn eq(&self, _other: &Underscore) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl ToTokens for Underscore

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

where Self: Sized,

Convert self directly into a TokenStream object.
