Function encode_u64 

pub fn encode_u64(value: u64, buf: &mut WriteBuf<'_>) -> Result<()>

Encode value as a u64 varint into buf.

Errors

Returns Error::BufferFull if buf has fewer than encoded_len_u64 bytes available. Nothing is written on error.

Example

use wire_codec::{varint, WriteBuf};
let mut out = [0u8; varint::MAX_LEN_U64];
let mut buf = WriteBuf::new(&mut out);
varint::encode_u64(u64::MAX, &mut buf).unwrap();
assert_eq!(buf.position(), 10);
