@rust-lang/libs how do you feel about adding this? |
This is similar to `NonNull::cast`. Compared to the `as` operator (which has a wide range of meanings depending on the input and output types), a call to this method: * Can only go from a raw pointer to a raw pointer * Cannot change the pointer’s `const`ness … even when the pointed types are inferred based on context.

I like the direction of this; it seems readable and particularly amenable for turbofish for added clarity. Moreover, it is constrained which seems like a plus in terms of local reasoning. |

Seems plausible to me. We might similarly want methods to go |
I would propose |
|
Or maybe only |
|
Agreed that it seems plausible to me (enough to land as unstable at least) |
|
Seems useful! @bors: r+ |
