New version of transmute, exposed under this name so it can be iterated upon without risking breakage to uses of "real" transmute.

Uses a const-assert to check the sizes instead of typeck hacks, but is semantially identical to transmute otherwise.

It will not be stabilized under this name.

Examples

#![feature(transmute_neo)]
use std::mem::transmute_neo;

assert_eq!(unsafe { transmute_neo::<f32, u32>(0.0) }, 0);

#![feature(transmute_neo)]
use std::mem::transmute_neo;

unsafe { transmute_neo::<u32, u16>(123) };
