How do I convert between numeric types?

I want to convert a u8 to an i32. I used to do:

use std::num::ToPrimitive;

fn main () {

    // ...
    // Other code
    // ...

    let int32 : i32 = u8Value.to_i32().unwrap();
}

This code does not compile in the recent nightlies. It complains that the ToPrimitive trait is unstable and will likely be removed.

Use as to cast numeric types:

fn main () {
    let u8_value: u8 = 42;
    let i32_value: i32 = u8_value as i32;
}
