Module rustc_infer::traits::project

Code for projecting associated types out of trait references.

Structs

• MismatchedProjectionTypes
• Normalized
• ProjectionCache
  The projection cache. Unlike the standard caches, this can include infcx-dependent type variables, therefore we have to roll the cache back each time we roll a snapshot back, to avoid assumptions on yet-unresolved inference variables. Types with placeholder regions also have to be removed when the respective snapshot ends.
