Struct TypeVar 

pub struct TypeVar<'db> {
    pub inference_id: InferenceId<'db>,
    pub id: LocalTypeVarId,
}

A type 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<'db>

id: LocalTypeVarId

Trait Implementations

impl<'db> Clone for TypeVar<'db>

fn clone(&self) -> TypeVar<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for TypeVar<'db>

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

Formats the value using the given formatter.

impl<'db> Hash for TypeVar<'db>

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<'db> PartialEq for TypeVar<'db>

fn eq(&self, other: &TypeVar<'db>) -> 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.

impl<'a, 'r> SemanticRewriter<TypeVar<'a>, DiagnosticAdded> for SubstitutionRewriter<'a, 'r>

fn internal_rewrite( &mut self, _value: &mut TypeVar<'a>, ) -> Result<RewriteResult, DiagnosticAdded>

fn rewrite(&mut self, value: T) -> Result<T, Error>

impl<'a, 'mt> SemanticRewriter<TypeVar<'a>, NoError> for Inference<'a, 'mt>

fn internal_rewrite( &mut self, _value: &mut TypeVar<'a>, ) -> Result<RewriteResult, NoError>

fn rewrite(&mut self, value: T) -> Result<T, Error>

impl<'db> Update for TypeVar<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Copy for TypeVar<'db>

impl<'db> Eq for TypeVar<'db>

impl<'db> StructuralPartialEq for TypeVar<'db>
