Expand description

Denotes the source of a region that is named by a RegionName. For example, a free region that was named by the user would get NamedFreeRegion and 'static lifetime would get Static. This helps to print the right kinds of diagnostics.

Variants

NamedEarlyBoundRegion(Span)
Expand description

NamedFreeRegion(Span)
Expand description

A free region that the user has a name ('a) for.

Static
Expand description

The 'static region.

SynthesizedFreeEnvRegion(Span, String)
Expand description

The free region corresponding to the environment of a closure.

AnonRegionFromArgument(RegionNameHighlight)
Expand description

The region corresponding to an argument.

AnonRegionFromUpvar(Span, String)
Expand description

The region corresponding to a closure upvar.

AnonRegionFromOutput(RegionNameHighlight, String)
Expand description

The region corresponding to the return type of a closure.

AnonRegionFromYieldTy(Span, String)
Expand description

The region from a type yielded by a generator.

AnonRegionFromAsyncFn(Span)
Expand description

An anonymous region from an async fn.
