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

Fields

next_constraint: Option<NllMemberConstraintIndex>definition_span: Span

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.
