Struct rustc_hir_analysis::check::wfcheck::GATArgsCollector
source · struct GATArgsCollector<'tcx> {
gat: DefId,
regions: FxHashSet<(Region<'tcx>, usize)>,
types: FxHashSet<(Ty<'tcx>, usize)>,
}
Expand description
TypeVisitor that looks for uses of GATs like
<P0 as Trait<P1..Pn>>::GAT<Pn..Pm>
and adds the arguments P0..Pm
into
the two vectors, regions
and types
(depending on their kind). For each
parameter Pi
also track the index i
.

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