此crate公开了derive宏，使Rust类型能够推导wrpc_transport::Encode和wrpc_transport::Receive特性。

示例

use wrpc_transport_derive::{Encode, Receive};

#[derive(Trace, PartialEq, Eq, Encode, Receive, Default)]
struct TestStruct {
    one: u32,
}

let mut buffer: Vec<u8> = Vec::new();
// Encode the TestStruct
TestStruct { one: 1 }
    .encode(&mut buffer)
    .await
    .context("failed to perform encode")?;

// Attempt to receive the value
let (received, leftover): (TestStruct, _) =
    Receive::receive_sync(Bytes::from(buffer), &mut empty())
        .await
        .context("failed to receive")?;

// At this point, we expect the received bytes to be exactly the same as what we started with
assert_eq!(received, TestStruct { one: 1 }, "received matches");
assert_eq!(leftover.remaining(), 0, "payload was completely consumed");

注意：此宏crate使用tracing，因此如果您想看到输入和输出令牌，请在命令（例如cargo build）前添加RUST_LOG=trace。
