pub struct Label { /* private fields */ }

Implementations

impl Label

pub fn parent(self, _db: &dyn HirDatabase) -> DefWithBody

pub fn name(self, db: &dyn HirDatabase) -> Name

Trait Implementations

impl Clone for Label

fn clone(&self) -> Label

Returns a copy 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 From<(DefWithBodyId, Idx<Label>)> for Label

fn from((parent, label_id): (DefWithBodyId, LabelId)) -> Self

Converts to this type from the input type.

impl HasSource for Label

type Ast = Label

fn source(self, db: &dyn HirDatabase) -> Option<InFile<Self::Ast>>

Fetches the definition’s source node. Using [crate::Semantics::source] is preferred when working with crate::Semantics, as that caches the parsed file in the semantics’ cache.

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.
