Module rustc_borrowck::region_infer

Modules

dump_mir 🔒
As part of generating the regions, if you enable -Zdump-mir=nll, we will generate an annotated copy of the MIR that includes the state of region inference. This code handles emitting the region context internal state.
graphviz 🔒
This module provides linkage between RegionInferenceContext and rustc_graphviz traits, specialized to attaching borrowck analysis data to rendered labels.
opaque_types 🔒
reverse_sccs 🔒
values

AppliedMemberConstraint 🔒
Each time that apply_member_constraint is successful, it appends one of these structs to the member_constraints_applied field. This is used in error reporting to trace out what happened.
BlameConstraint
RegionDefinition 🔒
RegionInferenceContext
TypeTest
A “type test” corresponds to an outlives constraint between a type and a lifetime, like T: 'x or <T as Foo>::Bar: 'x. They are translated from the Verify region constraints in the ordinary inference context.

Cause 🔒
N.B., the variants in Cause are intentionally ordered. Lower values are preferred when it comes to error messages. Do not reorder willy nilly.
ExtraConstraintInfo
RegionRelationCheckResult 🔒
When we have an unmet lifetime constraint, we try to propagate it outward (e.g. to a closure environment). If we can’t, it is an error.
