此 crate 包含 derive 宏，允许 Rust 类型派生 wrpc_transport::Encode 和 wrpc_transport::Receive 特性。

此 crate 旨在通过 wrpc-transport-derive 使用，它是包含此（内部）宏 crate 所需依赖项的伞形 crate。

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，因此如果您想查看输入和输出标记，请在命令（例如 cargo build）之前添加 RUST_LOG=trace。
