Renders a slice of integers (or anything else that supports the LowerHex or UpperHex traits) as hex. For example, this:
extern crate hex_slice;
use hex_slice::AsHex;
fn main() {
let foo = vec![0u32, 1 ,2 ,3];
println!("{:x}", foo.as_hex());
}Displays: [0 1 2 3] on standard output (available with cargo run --example trivial).
