pub fn to_msgpack<T: ToMessagePack>(value: &T, buf: &mut [u8]) -> Result<usize>Expand description
Serializes a value of type T into the provided buffer, returning the number of bytes written.
§Errors
Serialization can fail if T’s implementation of ToMessagePack returns an error,
or if the provided buffer is too small.
§Examples
#[derive(zerompk::ToMessagePack)]
struct Point {
x: i32,
y: i32,
}
fn main() {
let point = Point { x: 1, y: 2 };
let mut buf = [0u8; 10];
let bytes_written = zerompk::to_msgpack(&point, &mut buf).unwrap();
assert_eq!(bytes_written, 3);
assert_eq!(&buf[..bytes_written], &[0x92, 0x01, 0x02]);
}
