We are pleased to announce our [Logfire Rust SDK](https://github.com/pydantic/logfire-rust).
We build parts of the Logfire Platform in Rust for performance, and we've been using this SDK internally to
instrument our own platform for a while now (yes, we ourselves are happy users of Logfire!)

This SDK has been invaluable in helping us develop our own platform, and we're excited to be able to share it with you.
This is an initial release, so not all the options in our [Python SDK](https://github.com/pydantic/logfire) are yet supported, however
we're keen to reach feature parity and will prioritise what you [ask for](https://pydantic.dev/docs/logfire/get-started/help/).
In short:
* First-class SDK for Rust, to make `logfire` as quick to configure in Rust as it is in Python
* Built on top of `tracing`, `opentelemetry` and `log` crates, so should be a drop-in addition to your existing instrumentation
* Exposes `logfire::span!`, `logfire::info!` and other macros to expose the full feature set of Logfire (e.g. tags, attributes)

Please [let us know](https://pydantic.dev/docs/logfire/get-started/help/) what you think.
