Previously, we would lose one message to the portal upon failing to send it. We now mitigate this in two ways: 1. We also check the error from `poll_ready` and don't even pop a message off from our buffer. 2. If sending still fails, we re-queue it to the front of the buffer. In certain scenarios as discovered in logs from #4058, this might have caused a loss of the "answer" message from a gateway to the client, resulting in a state mismatch where the gateway thinks the connection is established and the client times out on waiting for the answer.
Rust development guide
Firezone uses Rust for all data plane components. This directory contains the Linux and Windows clients, and low-level networking implementations related to STUN/TURN.
We target the last stable release of Rust using rust-toolchain.toml.
If you are using rustup, that is automatically handled for you.
Otherwise, ensure you have the latest stable version of Rust installed.
