}
Expand description

The essential nodes of a desugared for loop as well as the entire span: for pat in arg { body } becomes (pat, arg, body). Return (pat, arg, body, span).

Fields

pat: &'tcx Pat<'tcx>

for loop item

arg: &'tcx Expr<'tcx>

IntoIterator argument

body: &'tcx Expr<'tcx>

for loop body

loop_id: HirId

Compare this against hir::Destination.target

span: Span

entire for loop span
