Trait Implementations

impl AstNode for Label

type Language = Lang

fn syntax(&self) -> &SyntaxNode<Self::Language>

fn can_cast(kind: <Self::Language as Language>::Kind) -> bool

fn cast(node: SyntaxNode<Self::Language>) -> Option<Self>

fn clone_for_update(&self) -> Self

where Self: Sized,

fn clone_subtree(&self) -> Self

where Self: Sized,

impl Clone for Label

fn clone(&self) -> Label

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Label

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

Formats the value using the given formatter.

impl Display for Label

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

Formats the value using the given formatter.

impl Hash for Label

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 PartialEq for Label

fn eq(&self, other: &Label) -> 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.
