Struct CanonicalTrait 

pub struct CanonicalTrait<'db> {
    pub id: ConcreteTraitId<'db>,
    pub mappings: ImplVarTraitItemMappings<'db>,
}

A canonical representation of a concrete trait that needs to be solved.

Fields

id: ConcreteTraitId<'db>

mappings: ImplVarTraitItemMappings<'db>

Implementations

impl<'db> CanonicalTrait<'db>

pub fn canonicalize( db: &'db dyn Database, source_inference_id: InferenceId<'db>, trait_id: ConcreteTraitId<'db>, impl_var_mappings: ImplVarTraitItemMappings<'db>, ) -> (Self, CanonicalMapping<'db>)

Canonicalizes a concrete trait that is part of an Inference.

pub fn embed( &self, inference: &mut Inference<'db, '_>, ) -> (CanonicalTrait<'db>, CanonicalMapping<'db>)

Embeds a canonical trait into an Inference.

Trait Implementations

impl<'db> Clone for CanonicalTrait<'db>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for CanonicalTrait<'db>

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

Formats the value using the given formatter.

impl<'db> Hash for CanonicalTrait<'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 CanonicalTrait<'db>

fn eq(&self, other: &CanonicalTrait<'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.
