Struct rustc_middle::infer::MemberConstraint[][src]

pub struct MemberConstraint<'tcx> {
    pub opaque_type_def_id: DefId,
    pub definition_span: Span,
    pub hidden_ty: Ty<'tcx>,
    pub member_region: Region<'tcx>,
    pub choice_regions: Lrc<Vec<Region<'tcx>>>,

Requires that region must be equal to one of the regions in choice_regions. We often denote this using the syntax:

R0 member of [O1..On]


opaque_type_def_id: DefId

The DefId of the opaque type causing this constraint: used for error reporting.

definition_span: Span

The span where the hidden type was instantiated.

hidden_ty: Ty<'tcx>

The hidden type in which member_region appears: used for error reporting.

member_region: Region<'tcx>

The region R0.

choice_regions: Lrc<Vec<Region<'tcx>>>

The options O1..On.
