Fields§

§tcx: TyCtxt<'tcx>§body: &'a Body<'tcx>§output: &'a mut Vec<Spanned<MonoItem<'tcx>>>§instance: Instance<'tcx>§move_size_spans: Vec<Span>

Spans for move size lints already emitted. Helps avoid duplicate lints.

§skip_move_size_check: bool

If true, we should temporarily skip move size checks, because we are processing an operand to a skip_move_check_fns function call.

§skip_move_check_fns: Vec<DefId>

Set of functions for which it is OK to move large data into.

Implementations§

source§

impl<'a, 'tcx> MirUsedCollector<'a, 'tcx>

source

pub fn monomorphize<T>(&self, value: T) -> Twhere T: TypeFoldable<TyCtxt<'tcx>>,

source

Trait Implementations§

source§

impl<'a, 'tcx> Visitor<'tcx> for MirUsedCollector<'a, 'tcx>

source§

fn visit_constant(&mut self, constant: &ConstOperand<'tcx>, location: Location)

This does not walk the constant, as it has been handled entirely here and trying to walk it would attempt to evaluate the ty::Const inside, which doesn’t necessarily work, as some constants cannot be represented in the type system.
