hex-slice

Renders a slice of integers (or anythign lese 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).
