pub struct Underscore<'a>(/* private fields */);

An underscore: _

Trait Implementations

impl<'a> AstNode<'a> for Underscore<'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 Underscore<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Underscore<'a>

impl<'a> Debug for Underscore<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Underscore<'a>

impl<'a> Hash for Underscore<'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.

impl<'a> PartialEq for Underscore<'a>

fn eq(&self, other: &Underscore<'a>) -> 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.
