Struct chalk_solve::logging_db::WriteOnDropRustIrDatabase

pub struct WriteOnDropRustIrDatabase<I, W, DB, P = DB> where
    I: Interner,
    W: Write,
    DB: RustIrDatabase<I>,
    P: Borrow<DB>,  { /* fields omitted */ }

Wraps a RustIrDatabase, and, when dropped, writes out all used definition to the given file.

Uses LoggingRustIrDatabase internally.

Uses a separate type, P, for the database stored inside to account for Arc or wrapping other storage mediums.

fn custom_clauses(&self) -> Vec<ProgramClause<I>>

Returns any "custom program clauses" that do not derive from Rust IR. Used only in testing the underlying solver.

fn associated_ty_data(&self, ty: AssocTypeId<I>) -> Arc<AssociatedTyDatum<I>>

Returns the datum for the associated type with the given id.

fn trait_datum(&self, trait_id: TraitId<I>) -> Arc<TraitDatum<I>>

Returns the datum for the definition with the given id.

fn adt_datum(&self, adt_id: AdtId<I>) -> Arc<AdtDatum<I>>

Returns the datum for the ADT with the given id.

fn generator_datum(
    &self,
    generator_id: GeneratorId<I>
) -> Arc<GeneratorDatum<I>>

Returns the generator datum for the generator with the given id.

fn generator_witness_datum(
    &self,
    generator_id: GeneratorId<I>
) -> Arc<GeneratorWitnessDatum<I>>

Returns the generator witness datum for the generator with the given id.

fn adt_repr(&self, id: AdtId<I>) -> AdtRepr

Returns the representation for the ADT definition with the given id.

fn impl_datum(&self, impl_id: ImplId<I>) -> Arc<ImplDatum<I>>

Returns the datum for the impl with the given id.

fn associated_ty_value(
    &self,
    id: AssociatedTyValueId<I>
) -> Arc<AssociatedTyValue<I>>

Returns the AssociatedTyValue with the given id.

fn opaque_ty_data(&self, id: OpaqueTyId<I>) -> Arc<OpaqueTyDatum<I>>

Returns the OpaqueTyDatum with the given id.

fn hidden_opaque_type(&self, id: OpaqueTyId<I>) -> Ty<I>

Returns the "hidden type" corresponding with the opaque type.

fn impls_for_trait(
    &self,
    trait_id: TraitId<I>,
    parameters: &[GenericArg<I>],
    binders: &CanonicalVarKinds<I>
) -> Vec<ImplId<I>>

Returns a list of potentially relevant impls for a given trait-id; we also supply the type parameters that we are trying to match (if known: these parameters may contain inference variables, for example). The implementor is permitted to return any superset of the applicable impls; chalk will narrow down the list to only those that truly apply. The parameters are provided as a "hint" to help the implementor do less work, but can be completely ignored if desired.

fn local_impls_to_coherence_check(&self, trait_id: TraitId<I>) -> Vec<ImplId<I>>

Returns the impls that require coherence checking. This is not the full set of impls that exist:

fn impl_provided_for(&self, auto_trait_id: TraitId<I>, ty: &TyKind<I>) -> bool

Returns true if there is an explicit impl of the auto trait auto_trait_id for the type ty. This is part of the auto trait handling -- if there is no explicit impl given by the user for ty, then we provide default impls (otherwise, we rely on the impls the user gave).

fn well_known_trait_id(
    &self,
    well_known_trait: WellKnownTrait
) -> Option<TraitId<I>>

Returns id of a trait lang item, if found

fn program_clauses_for_env(
    &self,
    environment: &Environment<I>
) -> ProgramClauses<I>

Calculates program clauses from an env. This is intended to call the program_clauses_for_env function and then possibly cache the clauses.

fn interner(&self) -> &I

fn is_object_safe(&self, trait_id: TraitId<I>) -> bool

Check if a trait is object safe

fn trait_name(&self, trait_id: TraitId<I>) -> String

Retrieves a trait's original name. No uniqueness guarantees, but must a valid Rust identifier.

fn adt_name(&self, adt_id: AdtId<I>) -> String

Retrieves a struct's original name. No uniqueness guarantees, but must a valid Rust identifier.

fn assoc_type_name(&self, assoc_ty_id: AssocTypeId<I>) -> String

Returns the datum for the fn definition with the given id.

fn fn_def_name(&self, fn_def_id: FnDefId<I>) -> String

Retrieves the name of a function definition. No uniqueness guarantees, but must a valid Rust identifier.

) -> ClosureKind

Gets the ClosureKind for a given closure and substitution.

fn closure_inputs_and_output(
    &self,
    closure_id: ClosureId<I>,
    substs: &Substitution<I>
) -> Binders<FnDefInputsAndOutputDatum<I>>

Gets the inputs and output for a given closure id and substitution. We pass both the ClosureId and it's Substituion to give implementors the freedom to store associated data in the substitution (like rustc) or separately (like chalk-integration).

fn closure_upvars(
    &self,
    closure_id: ClosureId<I>,
    substs: &Substitution<I>
) -> Binders<Ty<I>>

Gets the upvars as a Ty for a given closure id and substitution. There are no restrictions on the type of upvars.

fn closure_fn_substitution(
    &self,
    closure_id: ClosureId<I>,
    substs: &Substitution<I>
) -> Substitution<I>

Gets the substitution for the closure when used as a function. For example, for the following (not-quite-)rust code:
