Struct clippy_utils::higher::ForLoop

source ·
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

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
