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.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
