Reasons to create a region inference variable

See error_reporting module for more details

Variants

MiscVariable(Span)

Region variables created for ill-categorized reasons, mostly indicates places in need of refactoring

PatternRegion(Span)

Regions created by a &P or [...] pattern

AddrOfRegion(Span)

Regions created by & operator

Autoref(Span, AssocItem)

Regions created as part of an autoref of a method receiver

Coercion(Span)

Regions created as part of an automatic coercion

EarlyBoundRegion(Span, Symbol)

Region variables created as the values for early-bound regions

LateBoundRegion(Span, BoundRegion, LateBoundRegionConversionTime)

Region variables created for bound regions in a function or method that is called

UpvarRegion(UpvarId, Span)

BoundRegionInCoherence(Symbol)

NLL(NLLRegionVariableOrigin)

This origin is used for the inference variables that we create during NLL region processing.
