Struct ForLoop

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,
    pub label: Option<Label>,
}

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

label: Option<Label>

label

Implementations

impl<'tcx> ForLoop<'tcx>

pub fn hir(expr: &Expr<'tcx>) -> Option<Self>

Parses a desugared for loop

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.
