Function to_vec 

pub fn to_vec<T>(value: &T) -> Result<Vec<u8>>
where
    T: Serialize,

Serialize the given data structure T as a ROSMSG byte vector.

Serialization can fail if T’s implementation of Serialize decides to fail. It can also fail if the structure contains unsupported elements.

Examples

let data = to_vec(&String::from("Hello, World!")).unwrap();
assert_eq!(data, b"\x11\0\0\0\x0d\0\0\0Hello, World!");
