Module rustc_trait_selection::infer::region_constraints

See README.md.

Structs

• MemberConstraint
  Requires that region must be equal to one of the regions in choice_regions. We often denote this using the syntax:
• RegionConstraintCollector
• RegionConstraintData
  The full set of region constraints gathered up by the collector. Describes constraints between the region variables and other regions, as well as other conditions that must be verified, or assumptions that can be made.
• RegionConstraintStorage
• RegionSnapshot
• RegionVariableInfo
• Verify
• VerifyIfEq
  This is a “conditional bound” that checks the result of inference and supplies a bound if it ended up being relevant. It’s used in situations like this:

Enums

• Constraint
  Represents a constraint that influences the inference process.
• GenericKind
• VerifyBound
  Describes the things that some GenericKind value G is known to outlive. Each variant of VerifyBound can be thought of as a function:
