to_bytes

fn to_bytes(string s) -> Vec<byte>

use string::{to_bytes};

Encodes s as UTF-8 into a new Vec<byte>.

Always succeeds; the result has s.len() bytes. Use it to pass text to io::write and the other byte-based IO functions.

Parameters#

Returns#

Vec<byte>

Examples#

use string::{to_bytes};
use tests::assert;
let b = to_bytes("Hi");
assert!(b.len() == 2);
assert!(b[0] == 72 as byte && b[1] == 105 as byte);
