Enum ExprClosureArgs

#[non_exhaustive]
pub enum ExprClosureArgs {
    Empty {
        token: PipePipe,
    },
    List {
        open: Pipe,
        args: Vec<(FnArg, Option<Comma>)>,
        close: Pipe,
    },
}

Representation of closure arguments.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

Closure has no arguments.

Fields

token: PipePipe

The || token.

List

Closure has a list of arguments.

Fields

open: Pipe

The opening pipe for the argument group.

args: Vec<(FnArg, Option<Comma>)>

The arguments of the function.

close: Pipe

The closening pipe for the argument group.

Trait Implementations

impl Debug for ExprClosureArgs

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

Formats the value using the given formatter.

impl Parse for ExprClosureArgs

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

Parse the current item from the parser.

impl PartialEq for ExprClosureArgs

fn eq(&self, other: &ExprClosureArgs) -> 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 Spanned for ExprClosureArgs

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ExprClosureArgs

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

Turn the current item into tokens.

impl TryClone for ExprClosureArgs

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.
