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.
• ProjectionCacheKey
• ProjectionCacheStorage

Enums

• EvaluationResult
  The result of trait evaluation. The order is important here as the evaluation of a list is the maximum of the evaluations.
• ProjectionCacheEntry
• Reveal
  Depending on the stage of compilation, we want projection to be more or less conservative.

Type Aliases

• NormalizedTy
• UndoLog 🔒
