Struct Async

#[non_exhaustive]
pub struct Async {
    pub span: Span,
}

The async keyword.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

span: Span

Associated span.

Trait Implementations

impl Clone for Async

fn clone(&self) -> Async

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Async

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

Formats the value using the given formatter.

impl Hash for Async

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 OptionSpanned for Async

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for Async

fn parse(p: &mut Parser<'_>) -> Result<Self>

Parse the current item from the parser.

impl PartialEq for Async

fn eq(&self, other: &Async) -> 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 Peek for Async

fn peek(peeker: &mut Peeker<'_>) -> bool

Peek the parser for the given token.

impl Spanned for Async

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for Async

fn to_tokens( &self, _: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for Async

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Copy for Async

impl Eq for Async

impl StructuralPartialEq for Async
