## What it is
The official Rust implementation of the OpenTelemetry APIs and SDKs for instrumenting applications to emit traces, metrics, and logs. It exports telemetry to vendor-neutral backends such as Prometheus, Jaeger, and Zipkin via OTLP and other exporters.

## Use cases
- instrument a Rust service with distributed traces
- export metrics to Prometheus from Rust
- send logs and traces via OTLP to an observability backend
- correlate traces across microservices in Rust
- add vendor-neutral telemetry to a Rust application
- propagate context and baggage between services

## When to choose
- you need standards-based tracing, metrics, and logs in Rust
- you want to switch observability backends without changing instrumentation
- you need OTLP export to Jaeger, Prometheus, or commercial vendors

## When to avoid
- you need a full observability backend with storage and visualization
- you want zero-code auto-instrumentation, which is not offered for Rust
- you need a simple single-signal logger rather than a full telemetry SDK

## Facets
- artifact type: library
- maturity: active
- function: tracing, monitoring, logging, sdk
- domain: monitoring, developer-tools, microservices
- platform: rust, cross-platform
- tags: opentelemetry, telemetry, metrics, distributed-tracing, otlp, observability, jaeger, prometheus, zipkin
