Trait Implementations

impl AsId for VariantId

fn as_id(&self) -> Id

impl Clone for VariantId

fn clone(&self) -> VariantId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariantId

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

Formats the value using the given formatter.

impl From<EnumVariantId> for VariantId

fn from(it: EnumVariantId) -> VariantId

Converts to this type from the input type.

impl From<StructId> for VariantId

fn from(it: StructId) -> VariantId

Converts to this type from the input type.

impl From<UnionId> for VariantId

fn from(it: UnionId) -> VariantId

Converts to this type from the input type.

impl From<VariantId> for AttrDefId

fn from(vid: VariantId) -> Self

Converts to this type from the input type.

impl FromIdWithDb for VariantId

fn from_id(__id: Id, zalsa: &Zalsa) -> Self

impl HasChildSource<Idx<FieldData>> for VariantId

type Value = Either<TupleField, RecordField>

fn child_source( &self, db: &dyn DefDatabase, ) -> InFile<ArenaMap<LocalFieldId, Self::Value>>

impl HasModule for VariantId

fn module(&self, db: &dyn DefDatabase) -> ModuleId

Returns the enclosing module this thing is defined within.

fn krate(&self, db: &dyn DefDatabase) -> Crate

Returns the crate this thing is defined within.

impl HasResolver for VariantId

fn resolver(self, db: &dyn DefDatabase) -> Resolver<'_>

Builds a resolver for type references inside this def.

impl Hash for VariantId

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 VariantId

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