Casts to a pointer of another type
# Original
- [`<*T>::cast`][orig]
- [`NonNull::cast`]
# Similar Functions
- [`Pointer::cast`]
- [`NonNullPointer::cast`]
# Notes
The destination type must be `Sized`. Metadata (slice length, trait vtable,
etc.) cannot be conjured.
# Examples
```rust
use pointdexter::prelude::*;
let mut x = 0u32;
let ptr = Pointer::from(&mut x);
let nnp = NonNullPointer::new(ptr).unwrap();
let cast_ptr = ptr.cast::<i8>();
let cast_nnp = nnp.cast::<u8>();
```
