Expand description

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

Fields

next_constraint: Option<NllMemberConstraintIndex>opaque_type_def_id: DefId

The opaque type whose hidden type is being inferred. (Used in error reporting.)

definition_span: Span

The span where the hidden type was instantiated.

hidden_ty: Ty<'tcx>

The hidden type in which R0 appears. (Used in error reporting.)

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 be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
