You don't need anymore than that to match what C offers, C as in standard C, not in the folklore of C as a portable assembler. In fact you're freer in Rust than in C, because there is a simple, defined way to type-pun memory in Rust. > Your C program is free to define x as an array with four elements and then access x[6] anyway It's free to do anything, but you can't be sure that it will do that, because of the utterly weak specification.
