Fields§

§sup: RegionVid

The region SUP must outlive SUB…

§sub: RegionVid

Region that must be outlived.

§locations: Locations

Where did this constraint arise?

§span: Span

The Span associated with the creation of this constraint. This should be used in preference to obtaining the span from locations, since the locations may give a poor span in some cases (e.g. converting a constraint from a promoted).

§category: ConstraintCategory<'tcx>

What caused this constraint?

§variance_info: VarianceDiagInfo<'tcx>

Variance diagnostic information

§from_closure: bool

If this constraint is promoted from closure requirements.
