Struct ImplVar

pub struct ImplVar {
    pub inference_id: InferenceId,
    pub id: LocalImplVarId,
    pub concrete_trait_id: ConcreteTraitId,
    pub lookup_context: ImplLookupContext,
}

An impl variable, created when a generic type argument is not passed, and thus is not known yet and needs to be inferred.

Fields

inference_id: InferenceId

id: LocalImplVarId

concrete_trait_id: ConcreteTraitId

lookup_context: ImplLookupContext

Implementations

impl ImplVar

pub fn intern(&self, db: &dyn SemanticGroup) -> ImplVarId

Trait Implementations

impl Clone for ImplVar

fn clone(&self) -> ImplVar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImplVar

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

Formats the value using the given formatter.

impl<'a, T: ?Sized + Upcast<dyn SemanticGroup + 'static>> DebugWithDb<T> for ImplVar

fn fmt(&self, f: &mut Formatter<'_>, other_db: &T) -> Result

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

impl Hash for ImplVar

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> Intern<'a, dyn SemanticGroup + 'a, ImplVarId> for ImplVar

fn intern( self, db: &(impl Upcast<dyn SemanticGroup + 'a> + ?Sized), ) -> ImplVarId

impl<'a> LookupIntern<'a, dyn SemanticGroup + 'a, ImplVar> for ImplVarId

fn lookup_intern( &self, db: &(impl Upcast<dyn SemanticGroup + 'a> + ?Sized), ) -> ImplVar

impl PartialEq for ImplVar

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