This crate contains derive macros that enable Rust types to derive wrpc_transport::Encode
and wrpc_transport::Receive
traits.
This crate is intended to be used via wrpc-transport-derive
, the umbrella crate which hosts dependencies required by this (internal) macro crate.
Example
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");
NOTE: This macro crate uses tracing
, so if you'd like to see the input & output tokens, prepend your command (ex. cargo build
) with RUST_LOG=trace
.
