Function xsnappy::encode

pub fn encode(dst: &mut [u8], src: &[u8]) -> usize

Encode src to dst. The dst must be initialized with a certain length. Return the exact length of encoded data.

Examples:

use xsnappy::{max_encode_len, encode};

let mut src = b"hello world! hello world!";
let mut dst = vec![0; max_encode_len(src.len())];
let len = encode(&mut dst, src);
dst.resize(len, 0); // resize to exact length

Panics:

Panics if the length of dst is less then max_encode_len(src.len())
