Struct CanonicalTrait

pub struct CanonicalTrait {
    pub id: ConcreteTraitId,
    pub mappings: ImplVarTraitItemMappings,
}

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

Fields

id: ConcreteTraitId

mappings: ImplVarTraitItemMappings

Implementations

impl CanonicalTrait

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

Canonicalizes a concrete trait that is part of an Inference.

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

Embeds a canonical trait into an Inference.

Trait Implementations

impl Clone for CanonicalTrait

fn clone(&self) -> CanonicalTrait

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CanonicalTrait

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

Formats the value using the given formatter.

impl Hash for CanonicalTrait

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 CanonicalTrait

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