Function write_msgpack 

pub fn write_msgpack<T: ToMessagePack, W: Write>(
    writer: &mut W,
    value: &T,
) -> Result<()>

Serializes a value of type T into the I/O stream.

Errors

Serialization can fail if T’s implementation of ToMessagePack returns an error, or if the underlying I/O operation fails.

Examples

#[derive(zerompk::ToMessagePack)]
struct Point {  
   x: i32,
   y: i32,
}

fn main() {
    let point = Point { x: 1, y: 2 };
    let mut file = std::fs::File::open("point.msgpack").unwrap();
    zerompk::write_msgpack(&mut file, &point).unwrap();
}
