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

pub(crate) enum RegionNameHighlight {
    MatchedHirTy(Span),
    MatchedAdtAndSegment(Span),
    CannotMatchHirTy(Span, String),
}

Describes what to highlight to explain to the user that we're giving an anonymous region a synthesized name, and how to highlight it.

Variants

MatchedHirTy(Span)

The anonymous region corresponds to a reference that was found by traversing the type in the HIR.

MatchedAdtAndSegment(Span)

The anonymous region corresponds to a '_ in the generics list of a struct/enum/union.

CannotMatchHirTy(Span, String)

The anonymous region corresponds to a region where the type annotation is completely missing from the code, e.g. in a closure arguments |x| { ... }, where x is a reference.
