A high-performance, protocol-agnostic metrics ecosystem for Rust, centered on a lightweight metrics facade similar to the log crate. It lets library and application authors instrument code with counters, gauges, and histograms, and export those metrics to external systems via exporter crates.

Use cases

• instrument a Rust application to collect metrics in production
• count how many times a code path is hit
• track execution time of code with histograms
• expose internal counters and gauges in a standardized way
• capture tracing span fields as metric labels
• export Rust application metrics to monitoring systems

When to choose

• you're writing Rust and need application or library instrumentation
• you want a log-crate-style facade so instrumented libraries feed metrics into your app automatically
• you need protocol-agnostic metrics with pluggable exporters

When to avoid

• you need full observability (traces + logs + metrics) in one bundled solution rather than a metrics facade
• your project is not in Rust
• you only need system-level monitoring rather than application instrumentation
