Values computed by queries that use MIR.
Indicates an outlives-constraint between a type or between two free regions declared on the closure.
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.
The result of the
Coverage information summarized from a MIR if instrumented for source code coverage (see
-Cinstrument-coverage). This information is generated by the
InstrumentCoverage MIR pass and can be retrieved via the
The constituent parts of a type level constant of kind ADT or array.
The constituent parts of a mir constant of kind ADT or array.
The layout of generator state.
The subject of a
ClosureOutlivesRequirement – that is, the thing
that must outlive some region.
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.
