Struct rustc_const_eval::interpret::OpTy

pub struct OpTy<'tcx, Tag: Provenance = AllocId> {
    op: Operand<Tag>,

}

Fields

op: Operand<Tag>

layout: TyAndLayout<'tcx>

Implementations

impl<'tcx, Tag: Provenance> OpTy<'tcx, Tag>

pub fn try_as_mplace(&self) -> Result<MPlaceTy<'tcx, Tag>, ImmTy<'tcx, Tag>>

Note: do not call as_ref on the resulting place. This function should only be used to read from the resulting mplace, not to get its address back.

pub fn assert_mem_place(&self) -> MPlaceTy<'tcx, Tag>

Note: do not call as_ref on the resulting place. This function should only be used to read from the resulting mplace, not to get its address back.

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.
