Function to_bytes 

pub fn to_bytes<T: Encode>(value: &T) -> Vec<u8> 

Encodes value into a fresh Vec<u8>.

let bytes = cyclone_runtime::to_bytes(&Item { id: 42 });
assert_eq!(bytes, [0x2A, 0x00, 0x00, 0x00]);

Use Writer directly when several values share one buffer, or when a pre-sized buffer avoids reallocation.
