## What it is
The official Rust client library for Prometheus, ported from the Go client, for instrumenting Rust applications with metrics. It supports counters, gauges, histograms, static metrics, process metrics, and push gateways.

## Use cases
- expose prometheus metrics from a rust service
- add counters and histograms to a rust application
- instrument a rust web server for monitoring
- export process metrics in rust
- push metrics to a prometheus pushgateway from rust

## When to choose
- you need Prometheus-compatible metrics in a Rust application
- you want a mature client ported from the official Go client
- you need compile-time-optimized metric lookups with static metrics

## When to avoid
- you need OpenTelemetry-based tracing and metrics rather than Prometheus format
- your project is not in Rust

## Facets
- artifact type: library
- maturity: stable
- function: monitoring, logging
- domain: monitoring, developer-tools, backend
- platform: rust, cross-platform
- tags: prometheus, metrics, instrumentation, observability
