This has been fixed.</li> </ul> <h2>0.3.42 [2025-08-31]</h2> <h3>Added</h3> <ul> <li><code>Time::duration_until</code></li> <li><code>Time::duration_since</code></li> <li><code>per_t</code> method for all types in <code>time::convert</code>. This is similar to the existing <code>per</code> method, but can return any of the primitive numeric types that can represent the result. This will cut down on <code>as</code> casts while ensuring correctness. Type inference isn't perfect, so you may need to provide a type annotation in some situations.</li> <li><code>impl PartialOrd for Month</code> and <code>impl Ord for Month</code>; this assumes the months are in the same year</li> <li><code>SystemTimeExt</code> trait, adding methods for checked arithmetic with <code>time::Duration</code> and obtaining the difference between two <code>SystemTime</code>s as a <code>time::Duration</code></li> <li>Permit using <code>UtcDateTime</code> with <code>rand</code> (this was inadvertently omitted previously)</li> <li><code>impl core::error::Error</code> for all error types (now available when the <code>std</code> feature is disabled)</li> <li>MacOS can now obtain the local UTC offset in multi-threaded programs as the system APIs are thread-safe.</li> <li><code>#[track_caller]</code> has been added to all relevant methods.</li> </ul> <h3>Changed</h3> <ul> <li>The minimum supported Rust version is now 1.81.0.</li> <li>The dependency on <code>itoa</code> has been removed, as the standard library now has similar functionality by default.</li> <li>Formatting a component that involves a floating point number is now guaranteed to be deterministic, avoiding any subtle differences between platforms or compiler versions.</li> </ul> <h3>Fixed</h3> <ul> <li>Serializing timestamps with nanosecond precision <em>should</em> always emit the correct value. Previously, it could be off by one nanosecond due to floating point imprecision.</li> <li>A previously unknown bug in <code>OffsetDateTime::to_offset</code> and <code>UtcDateTime::to_offset</code> has been fixed. The bug could result in a value that was invalid. It was unlikely to ever occur in real-world code, as it involved passing a UTC offset that has never been used in any location.</li> </ul> <h3>Miscellaneous</h3> <ul> <li>The amount of code generated by macros has been massively reduced, on the order of 65-70% for typical use cases of <code>format_description!</code>.</li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...

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.
Reading Client logs
The Client logs are written as JSONL for machine-readability.
To make them more human-friendly, pipe them through jq like this:
cd path/to/logs # e.g. `$HOME/.cache/dev.firezone.client/data/logs` on Linux
cat *.log | jq -r '"\(.time) \(.severity) \(.message)"'
Resulting in, e.g.
2024-04-01T18:25:47.237661392Z INFO started log
2024-04-01T18:25:47.238193266Z INFO GIT_VERSION = 1.0.0-pre.11-35-gcc0d43531
2024-04-01T18:25:48.295243016Z INFO No token / actor_name on disk, starting in signed-out state
2024-04-01T18:25:48.295360641Z INFO null
Benchmarking on Linux
The recommended way for benchmarking any of the Rust components is Linux' perf utility.
For example, to attach to a running application, do:
- Ensure the binary you are profiling is compiled with the
releaseprofile. sudo perf record -g --freq 10000 --pid $(pgrep <your-binary>).- Run the speed test or whatever load-inducing task you want to measure.
sudo perf script > profile.perf- Open profiler.firefox.com and load
profile.perf
Instead of attaching to a process with --pid, you can also specify the path to executable directly.
That is useful if you want to capture perf data for a test or a micro-benchmark.
