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

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.
