Represents a R0 member of [R1..Rn] constraint

Fields

next_constraint: Option<NllMemberConstraintIndex>definition_span: Span

key: OpaqueTypeKey<'tcx>member_region_vid: RegionVid

The region R0.

start_index: usize

Index of R1 in choice_regions vector from MemberConstraintSet.

end_index: usize

Index of Rn in choice_regions vector from MemberConstraintSet.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
