Module rustc_middle::mir::query

Values computed by queries that use MIR.

Structs

• BorrowCheckResult
• ClosureOutlivesRequirement
  Indicates an outlives-constraint between a type or between two free regions declared on the closure.
• ClosureOutlivesSubjectTy
  Represents a ty::Ty for use in ClosureOutlivesSubject.
• ClosureRegionRequirements
  After we borrow check a closure, we are left with various requirements that we have inferred between the free regions that appear in the closure’s signature or on its field types. These requirements are then verified and proved by the closure’s creating function. This struct encodes those requirements.
• ConstQualifs
  The result of the mir_const_qualif query.
• CoroutineLayout
  The layout of coroutine state.
• CoroutineSavedLocal
• CoroutineSavedTy
• CoverageIdsInfo
  Summarizes coverage IDs inserted by the InstrumentCoverage MIR pass (for compiler option -Cinstrument-coverage), after MIR optimizations have had a chance to potentially remove some of them.
• DestructuredConstant
  The constituent parts of a mir constant of kind ADT or array.

Enums

• ClosureOutlivesSubject
  The subject of a ClosureOutlivesRequirement – that is, the thing that must outlive some region.
• ConstraintCategory
  Outlives-constraints can be categorized to determine whether and why they are interesting (for error reporting). Order of variants indicates sort order of the category, thereby influencing diagnostic output.
• ReturnConstraint
