Struct rustc_infer::infer::region_constraints::MemberConstraint[−][src]

pub struct MemberConstraint<'tcx> {
    pub opaque_type_def_id: DefId,
    pub definition_span: Span,
    pub hidden_ty: &'tcx TyS<'tcx>,
    pub member_region: &'tcx RegionKind,
    pub choice_regions: Rc<Vec<&'tcx RegionKind, Global>>,
}
Expand description

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]

Fields

opaque_type_def_id: DefId
Expand description

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

definition_span: Span
Expand description

The span where the hidden type was instantiated.

hidden_ty: &'tcx TyS<'tcx>
Expand description

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

member_region: &'tcx RegionKind
Expand description

The region R0.

choice_regions: Rc<Vec<&'tcx RegionKind, Global>>
Expand description

The options O1..On.
