Module imp

Structs

• ConcreteImplId
• ConcreteImplLongId
• GeneratedImplId
• GeneratedImplItems
• GeneratedImplLongId
  An impl that is generated by the compiler for a specific trait. There can be only one such impl per concrete trait as otherwise there would be a MultipleImplsFound ambiguity.
• ImplDeclarationData
• ImplDefinitionData
• ImplFunctionDeclarationData
• ImplId
• ImplImplId
  An impl item of kind impl.
• ImplItemConstantData
• ImplItemImplData
• ImplItemTypeData
• ImplLookupContext
• ImplicitImplImplData
• TraitFilter
  A filter for trait lookup that is not based on current inference state. This is used for caching queries.
• UninferredGeneratedImplId
• UninferredGeneratedImplLongId
  Generated impls before inference, see GeneratedImplLongId for more details.

Enums

• GeneratedImplAssociatedTypes
• GenericsHeadFilter
  A lookup filter on generic arguments that is not based on current inference state. This is used for caching queries.
• ImplHead
  Head of an impl.
• ImplLongId
  Represents a “callee” impl that can be referred to in the code. Traits should be resolved to this.
• ImplOrModuleById
• UninferredImpl
  An candidate impl for later inference.
