# Prometheus Rust client library
[](https://github.com/tikv/rust-prometheus/actions/workflows/rust.yml)
[](https://docs.rs/prometheus)
[](https://crates.io/crates/prometheus)
This is the [Rust](https://www.rust-lang.org) client library for
[Prometheus](http://prometheus.io). The main data structures and APIs are ported
from [Go client](https://github.com/prometheus/client_golang).
## Documentation
Find the latest documentation at <https://docs.rs/prometheus>.
## Advanced
### Crate features
This crate provides several optional components which can be enabled via [Cargo `[features]`](https://doc.rust-lang.org/cargo/reference/features.html):
- `gen`: To generate protobuf client with the latest protobuf version instead of
using the pre-generated client.
- `nightly`: Enable nightly only features.
- `process`: Enable [process metrics](https://prometheus.io/docs/instrumenting/writing_clientlibs/#process-metrics) support.
- `push`: Enable [push metrics](https://prometheus.io/docs/instrumenting/pushing/) support.
### Static Metric
When using a `MetricVec` with label values known at compile time
prometheus-static-metric reduces the overhead of retrieving the concrete
`Metric` from a `MetricVec`.
See [static-metric](./static-metric) directory for details.
