Trait Implementations

impl<'a> AstNode<'a> for None<'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 span(self) -> Span

The source code location.

impl<'a> Clone for None<'a>

fn clone(&self) -> None<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for None<'a>

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

Formats the value using the given formatter.

impl Default for None<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Hash for None<'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 None<'a>

fn eq(&self, other: &None<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
