Enum rustc_const_eval::interpret::FnArg

pub enum FnArg<'tcx, Prov: Provenance = AllocId> {
    Copy(OpTy<'tcx, Prov>),
    InPlace(PlaceTy<'tcx, Prov>),
}

An argment passed to a function.

Variants

Copy(OpTy<'tcx, Prov>)

Pass a copy of the given operand.

InPlace(PlaceTy<'tcx, Prov>)

Allow for the argument to be passed in-place: destroy the value originally stored at that place and make the place inaccessible for the duration of the function call.

Implementations

impl<'tcx, Prov: Provenance> FnArg<'tcx, Prov>

pub fn layout(&self) -> &TyAndLayout<'tcx>

Trait Implementations

impl<'tcx, Prov: Clone + Provenance> Clone for FnArg<'tcx, Prov>

fn clone(&self) -> FnArg<'tcx, Prov>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx, Prov: Debug + Provenance> Debug for FnArg<'tcx, Prov>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
