Module rustc_utils 

Traits

HasParamEnv

SubstBinder

Functions

assoc_tys_for_trait

Generates a list of <trait_ref>::Ty type aliases for each non-gat associated type of the given trait and its parents, in a specific order.

attribute_from_scope 🔒

can_have_generics 🔒

Whether the item can have generic parameters.

closure_once_shim

drop_glue_shim

dyn_self_ty

Generates a dyn Trait<Args.., Ty = <Self as Trait>::Ty..> type for the given trait ref.

get_closest_parent_type

Gets the closest ancestor of id that is the id of a type.

get_def_attrs

Gets the attributes of the definition.

get_def_visibility

Gets the visibility (pub or not) of the definition. Returns None for defs that don’t have a meaningful visibility.

get_foreign_mod_children

Gets the children of an extern block. Empty if the block is not defined in the current crate.

get_method_sig

The signature of a method impl may be a subtype of the one expected from the trait decl, as in the example below. For correctness, we must be able to map from the method generics declared in the trait to the actual method generics. Because this would require type inference, we instead simply return the declared signature. This will cause issues if it is possible to use such a more-specific implementation with its more-specific type, but we have a few other issues with lifetime-generic function pointers anyway so this is unlikely to cause problems.

get_mod_children

Gets the children of a module.

get_variant_information 🔒
