Variants§

§

§

Spread(Spread<'a>)

A destructuring sink: ..y or ...

Trait Implementations§

Source§

impl<'a> AstNode<'a> for DestructuringItem<'a>

Source§

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

Convert a node into its typed variant.
Source§

fn to_untyped(self) -> &'a SyntaxNode

A reference to the underlying syntax node.
Source§

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.
Source§

fn span(self) -> Span

The source code location.
