Structs

• EvalCtxt
• ExternalConstraintsData
  Additional constraints returned on success.
• FulfillmentCtxt
  A trait engine using the new trait solver.
• Goal
  A goal is a statement, i.e. predicate, we want to prove given some assumptions, i.e. param_env.
• NestedNormalizationGoals
• NoSolution
• PredefinedOpaquesData
  Opaques that are defined in the inference context before a query is called.
• QueryInput
• Response

Enums

• BuiltinImplSource
• CandidateSource
  Possible ways the given goal can be proven.
• Certainty
• GenerateProofTree
• GoalSource
  Why a specific goal has to be proven.
• MaybeCause
  Why we failed to evaluate a goal.
• NextSolverError
• Reveal
  Depending on the stage of compilation, we want projection to be more or less conservative.
• SolverMode

Traits

• InferCtxtSelectExt
• SolverDelegateEvalExt

Functions

• deeply_normalize
  Deeply normalize all aliases in value. This does not handle inference and expects its input to be already fully resolved.
• deeply_normalize_with_skipped_universes
  Deeply normalize all aliases in value. This does not handle inference and expects its input to be already fully resolved.

Type Aliases

• CanonicalInput
• CanonicalResponse
• QueryResult
  The result of evaluating a canonical query.
