Expand description
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.
Occluded(Span, String)
The anonymous region corresponds to a region where the type annotation is completely missing
from the code, and even if we print out the full name of the type, the region name won’t
be included. This currently occurs for opaque types like impl Future
.
