Module elaborate

Structs

• ClauseWithSupertraitSpan
• Elaborator
  “Elaboration” is the process of identifying all the predicates that are implied by a source predicate. Currently, this basically means walking the “supertraits” and other similar assumptions. For example, if we know that T: Ord, the elaborator would deduce that T: PartialOrd holds as well. Similarly, if we have trait Foo: 'static, and we know that T: Foo, then we know that T: 'static.
• FilterToTraits
  A filter around an iterator of predicates that makes it yield up just trait references.

Enums

• Filter 🔒

Traits

• Elaboratable
  Describes how to elaborate an obligation into a sub-obligation.

Functions

• elaborate
• elaborate_component_to_clause 🔒
• supertrait_def_ids
  Computes the def-ids of the transitive supertraits of trait_def_id. This (intentionally) does not compute the full elaborated super-predicates but just the set of def-ids. It is used to identify which traits may define a given associated type to help avoid cycle errors, and to make size estimates for vtable layout computation.
