    Pos(Expr<'a>),
    Named(Named<'a>),
    Spread(Spread<'a>),
}

An argument to a function call.

Variants

Pos(Expr<'a>)

Trait Implementations

impl<'a> AstNode<'a> for Arg<'a>

fn from_untyped(node: &'a SyntaxNode) -> Option<Self>

Convert a node into its typed variant.

fn to_untyped(self) -> &'a SyntaxNode

A reference to the underlying syntax node.

fn placeholder() -> Self

A placeholder for this node type. If the underlying CST has syntax errors or did not come from the parser, the AST is not guaranteed to be valid. But instead of panicking in that case, we return placeholder nodes.

fn span(self) -> Span

The source code location.

impl<'a> Clone for Arg<'a>

fn clone(&self) -> Arg<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Arg<'a>

impl<'a> Debug for Arg<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Arg<'a>

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.
