macro_rules! protobuf_message_decoder {
    () => { ... };
    ($field:tt) => { ... };
    ($($field:tt),*) => { ... };
}

Macro for creating an instance of a message decoder.

Examples

use bytecodec::DecodeExt;
use protobuf_codec::field::num::{F1, F2};
use protobuf_codec::scalar::Int32Decoder;

// syntax = "proto3";
//
// message Pair {
//   int32 aaa = 1;
//   int32 bbb = 2;
// }

let mut decoder = protobuf_message_decoder![
    (F1, Int32Decoder::new()),
    (F2, Int32Decoder::new(), required)
];
assert_eq!(decoder.decode_from_bytes(&[8, 1, 16, 2][..]).unwrap(), (1, 2));
