Fields of TypeTestError

type_test: TypeTest<'tcx>
UnexpectedHiddenRegion
Expand description

An unexpected hidden region for an opaque type.

Show fields

Fields of UnexpectedHiddenRegion

span: Span
Expand description

The span for the member constraint.

hidden_ty: Ty<'tcx>
Expand description

The hidden type.

member_region: Region<'tcx>
Expand description

The unexpected region.

BoundUniversalRegionError
Expand description

Higher-ranked subtyping error.

Show fields

Fields of BoundUniversalRegionError

longer_fr: RegionVid
Expand description

The placeholder free region.

error_element: RegionElement
Expand description

The region element that erroneously must be outlived by longer_fr.

fr_origin: NllRegionVariableOrigin
Expand description

The origin of the placeholder region.

RegionError
Expand description

Any other lifetime error.

Show fields

Fields of RegionError

fr_origin: NllRegionVariableOrigin
Expand description

The origin of the region.

longer_fr: RegionVid
Expand description

The region that should outlive shorter_fr.

shorter_fr: RegionVid
Expand description

The region that should be shorter, but we can’t prove it.

is_reported: bool
Expand description

Indicates whether this is a reported error. We currently only report the first error encountered and leave the rest unreported so as not to overwhelm the user.
