Struct CallArgs 

pub struct CallArgs<'ast> {
    pub span: Span,
    pub kind: CallArgsKind<'ast>,
}

A list of function call arguments.

Fields

span: Span

The span of the arguments. This points to the parenthesized list of arguments.

If the list is empty, this points to the empty ()/({}) or to where the ( would be.

kind: CallArgsKind<'ast>

Implementations

impl<'ast> CallArgs<'ast>

pub fn empty(span: Span) -> CallArgs<'ast>

Creates a new empty list of arguments.

span should be an empty span.

pub fn is_dummy(&self) -> bool

Returns true if the argument list is not present in the source code.

For example, a modifier m can be invoked in a function declaration as m or m(). In the first case, this returns true, and the span will point to after m. In the second case, this returns false.

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 + DoubleEndedIterator + Clone

Returns an iterator over the expressions.

pub fn exprs_mut(&mut self) -> impl ExactSizeIterator + DoubleEndedIterator

Returns an iterator over the expressions.

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

Formats the value using the given formatter.
