Implementations

impl<'db> ImplLookupContext<'db>

pub fn new_from_crate(crate_id: CrateId<'db>) -> Self

Creates a new ImplLookupContext from a CrateId.

pub fn new_from_type(ty: TypeId<'db>, db: &'db dyn Database) -> Self

Creates a new ImplLookupContext from a TypeId with the crate being the crate of the type’s module.

pub fn new( module_id: ModuleId<'db>, generic_params: Vec<GenericParamId<'db>>, db: &'db dyn Database, ) -> ImplLookupContext<'db>

Creates a new ImplLookupContext from a ModuleId.

pub fn insert_lookup_scope( &mut self, db: &'db dyn Database, imp: &UninferredImpl<'db>, )

pub fn insert_module(&mut self, module_id: ModuleId<'db>, db: &'db dyn Database)

Inserts a module into the lookup context, extending the inner impls with the module’s impls.

pub fn insert_impl(&mut self, impl_id: ImplId<'db>, db: &'db dyn Database)

Inserts an impl into the lookup context, extending the inner impls with the impl’s trait impls.

pub fn strip_for_trait_id(&mut self, db: &dyn Database, trait_id: TraitId<'db>)

Strips the lookup context of all impls that are not reachable in the dependency graph from the given trait.

Trait Implementations

impl<'db> Clone for ImplLookupContext<'db>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for ImplLookupContext<'db>

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

Formats the value using the given formatter.

impl<'db> DebugWithDb<'db> for ImplLookupContext<'db>

type Db = dyn Database

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

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

where Self: Sized + 'me,

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

where Self: Sized + 'me,

impl<'db> Hash for ImplLookupContext<'db>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

impl<'db> Intern<'db, ImplLookupContextId<'db>> for ImplLookupContext<'db>

fn intern(self, db: &'db dyn Database) -> ImplLookupContextId<'db>

impl<'db> PartialEq for ImplLookupContext<'db>

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