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.
