Implementations

impl Inference<'_>

pub fn reduce_impl_ty( &mut self, impl_type_id: ImplTypeId, ) -> InferenceResult<TypeId>

Reduces an impl type to a concrete type.

pub fn reduce_impl_constant( &mut self, impl_const_id: ImplConstantId, ) -> InferenceResult<ConstValueId>

Reduces an impl constant to a concrete const.

pub fn reduce_impl_impl( &mut self, impl_impl_id: ImplImplId, ) -> InferenceResult<ImplId>

Reduces an impl impl to a concrete impl.

pub fn rewritten_impl_type( &mut self, id: ImplVarId, trait_type_id: TraitTypeId, ) -> TypeId

Returns the type of an impl var’s type item. The type may be a variable itself, but it may previously exist, so may be more specific due to rewriting.

pub fn rewritten_impl_constant( &mut self, id: ImplVarId, trait_constant: TraitConstantId, ) -> ConstValueId

Returns the constant value of an impl var’s constant item. The constant may be a variable itself, but it may previously exist, so may be more specific due to rewriting.

pub fn rewritten_impl_impl( &mut self, id: ImplVarId, concrete_trait_impl: ConcreteTraitImplId, ) -> ImplId

Returns the inner_impl value of an impl var’s impl item. The inner_impl may be a variable itself, but it may previously exist, so may be more specific due to rewriting.

pub fn conform_ty_for_diag( &mut self, ty0: TypeId, ty1: TypeId, ) -> Result<(), (ErrorSet, TypeId, TypeId)>

Conforms a type to a type. Returning the reduced types on failure. Useful for immediately reporting a diagnostic based on the compared types.

impl<'db> Inference<'db>

pub fn impl_assignment(&self, var_id: LocalImplVarId) -> Option<ImplId>

Getter for an impl var assignment.

pub fn new_type_var(&mut self, stable_ptr: Option<SyntaxStablePtrId>) -> TypeId

Allocates a new TypeVar for an unknown type that needs to be inferred. Returns a wrapping TypeId.

pub fn new_type_var_raw( &mut self, stable_ptr: Option<SyntaxStablePtrId>, ) -> TypeVar

Allocates a new TypeVar for an unknown type that needs to be inferred. Returns the variable id.

pub fn impl_type_assignment(&mut self, impl_type: ImplTypeId) -> TypeId

Getter for an impl type assignment. Creates a new type var if the impl type is not yet assigned.

pub fn finalize_impl_type_bounds(&mut self)

If an impl type is not fully inferred, we assign it’s var to the original type

pub fn new_const_var( &mut self, stable_ptr: Option<SyntaxStablePtrId>, ty: TypeId, ) -> ConstValueId

Allocates a new ConstVar for an unknown consts that needs to be inferred. Returns a wrapping ConstValueId.

Allocates a new ImplVar for an unknown type that needs to be inferred. Returns a wrapping ImplId.

pub fn solve(&mut self) -> InferenceResult<()>

Solves the inference system. After a successful solve, there are no more pending impl inferences. Returns whether the inference was successful. If not, the error may be found by .error_state().

pub fn solution_set(&mut self) -> InferenceResult<SolutionSet<()>>

Returns the solution set status for the inference: Whether there is a unique solution, multiple solutions, no solutions or an error.

pub fn finalize_without_reporting( &mut self, ) -> Result<(), (ErrorSet, Option<SyntaxStablePtrId>)>

Finalizes the inference by inferring uninferred numeric literals as felt252. Returns an error and does not report it.

pub fn finalize( &mut self, diagnostics: &mut SemanticDiagnostics, stable_ptr: SyntaxStablePtrId, )

Finalizes the inference and report diagnostics if there are any errors. All the remaining type vars are mapped to the missing type, to prevent additional diagnostics.

pub fn trait_solution_set( &mut self, concrete_trait_id: ConcreteTraitId, lookup_context: ImplLookupContext, ) -> InferenceResult<SolutionSet<(CanonicalImpl, CanonicalMapping)>>

Computes the solution set for a trait with a recursive query.

pub fn set_error(&mut self, err: InferenceError) -> ErrorSet

Sets an error in the inference state. Does nothing if an error is already set. Returns an ErrorSet that can be used in reporting the error.

pub fn is_error_set(&self) -> InferenceResult<()>

Returns whether an error is set (either pending or consumed).

pub fn consume_error_without_reporting( &mut self, err_set: ErrorSet, ) -> Option<InferenceError>

Consumes the error but doesn’t report it. If there is no error, or the error is consumed, returns None. This should be used with caution. Always prefer to use (1) report_on_pending_error if possible, or (2) consume_reported_error which is safer.

Gets an ErrorSet to “enforce” it is only called when an error is set.

pub fn consume_reported_error( &mut self, err_set: ErrorSet, diag_added: DiagnosticAdded, )

Consumes the error that is already reported. If there is no error, or the error is consumed, does nothing. This should be used with caution. Always prefer to use report_on_pending_error if possible.

Gets an ErrorSet to “enforce” it is only called when an error is set. Gets an DiagnosticAdded to “enforce” it is only called when a diagnostic was reported.

pub fn report_on_pending_error( &mut self, _err_set: ErrorSet, diagnostics: &mut SemanticDiagnostics, stable_ptr: SyntaxStablePtrId, ) -> DiagnosticAdded

Consumes the pending error, if any, and reports it. Should only be called when an error is set, otherwise it panics. Gets an ErrorSet to “enforce” it is only called when an error is set. If an error was set but it’s already consumed, it doesn’t report it again but returns the stored DiagnosticAdded.

pub fn report_modified_if_pending( &mut self, err_set: ErrorSet, report: impl FnOnce() -> DiagnosticAdded, )

If the current status is of a pending error, reports an alternative diagnostic, by calling report, and consumes the error. Otherwise, does nothing.
