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.

§

DynStar

Casting into a dyn* value.

Implementations§

source§

impl<'tcx> CastTy<'tcx>

source

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

Returns Some for integral/pointer casts. Casts like unsizing casts will return None.

source§

impl<'tcx> PartialEq for CastTy<'tcx>

source§

fn eq(&self, other: &CastTy<'tcx>) -> bool
