Enum rustc_middle::ty::cast::CastTy

source · [−]

pub enum CastTy<'tcx> {
    Int(IntTy),
    Float,
    FnPtr,
    Ptr(TypeAndMut<'tcx>),
}

Variants

`Int(IntTy)`

Various types that are represented as ints and handled mostly in the same way, merged for easier matching.

`Float`

Floating-point types.

`FnPtr`

Function pointers.

`Ptr(TypeAndMut<'tcx>)`

Raw pointers.

Implementations

source

impl<'tcx> CastTy<'tcx>

source

pub fn from_ty(t: Ty<'tcx>) -> Option<CastTy<'tcx>>
