pub struct ForLoop<'tcx> {
    pub pat: &'tcx Pat<'tcx>,
    pub arg: &'tcx Expr<'tcx>,
    pub body: &'tcx Expr<'tcx>,
    pub loop_id: HirId,
    pub span: Span,
}
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). Returns (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
