Enum CallArgsKind 

pub enum CallArgsKind<'ast> {
    Unnamed(BoxSlice<'ast, Box<'ast, Expr<'ast>>>),
    Named(NamedArgList<'ast>),
}

A list of function call argument expressions.

Variants

Unnamed(BoxSlice<'ast, Box<'ast, Expr<'ast>>>)

A list of unnamed arguments: (1, 2, 3).

Named(NamedArgList<'ast>)

A list of named arguments: ({x: 1, y: 2, z: 3}).

Implementations

impl<'ast> CallArgsKind<'ast>

pub fn empty() -> Self

Creates a new empty list of unnamed arguments.

pub fn len(&self) -> usize

Returns the length of the arguments.

pub fn is_empty(&self) -> bool

Returns true if the list of arguments is empty.

pub fn exprs( &self, ) -> impl ExactSizeIterator<Item = &Expr<'ast>> + DoubleEndedIterator + Clone

Returns an iterator over the expressions.

pub fn exprs_mut( &mut self, ) -> impl ExactSizeIterator<Item = &mut Box<'ast, Expr<'ast>>> + DoubleEndedIterator

Returns an iterator over the expressions.

pub fn span(&self) -> Option<Span>

Returns the span of the argument expressions. Does not include the parentheses.

Trait Implementations

impl<'ast> Debug for CallArgsKind<'ast>

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

Formats the value using the given formatter.

impl Default for CallArgsKind<'_>

fn default() -> Self

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
