[−][src]Enum rustc_mir::borrow_check::diagnostics::region_name::RegionNameSource

pub(crate) enum RegionNameSource {
    NamedEarlyBoundRegion(Span),
    NamedFreeRegion(Span),
    Static,
    SynthesizedFreeEnvRegion(Span, String),
    AnonRegionFromArgument(RegionNameHighlight),
    AnonRegionFromUpvar(Span, String),
    AnonRegionFromOutput(RegionNameHighlight, String),
    AnonRegionFromYieldTy(Span, String),
    AnonRegionFromAsyncFn(Span),
}

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)

A bound (not free) region that was substituted at the def site (not an HRTB).

NamedFreeRegion(Span)

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

Static

The 'static region.

SynthesizedFreeEnvRegion(Span, String)

The free region corresponding to the environment of a closure.

AnonRegionFromArgument(RegionNameHighlight)

The region corresponding to an argument.

AnonRegionFromUpvar(Span, String)

The region corresponding to a closure upvar.

AnonRegionFromOutput(RegionNameHighlight, String)

The region corresponding to the return type of a closure.

AnonRegionFromYieldTy(Span, String)

The region from a type yielded by a generator.

AnonRegionFromAsyncFn(Span)

An anonymous region from an async fn.
