Function encode_u64

pub fn encode_u64(buf: &mut [u8; 9], value: u64) -> usize

Encodes a u64 into a buffer, returning the encoded length.

The contents of the buffer beyond the returned length are unspecified.

Examples

let mut buf = [0u8; 9];
let encoded_len = vu128::encode_u64(&mut buf, 12345);
assert_eq!(&buf[..encoded_len], &[0xB9, 0xC0]);
