# tracely
Unified observability library for Rust: distributed tracing, metrics, and structured logging in one package.
## Features
- **Distributed Tracing**: OpenTelemetry-compatible spans
- **Metrics**: Counters, gauges, histograms
- **Structured Logging**: Zero-allocation JSON logs
- **Exporters**: OTLP, Prometheus, Jaeger, Zipkin
## Installation
```toml
[dependencies]
tracely = { git = "https://github.com/KooshaPari/tracely" }
```
## Usage
```rust
use tracely::{tracer, metrics, log};
// Trace
let span = tracer::start("process_request");
defer { span.end(); }
// Metrics
metrics::counter!("requests_total").inc();
metrics::histogram!("request_duration").observe(duration);
// Log
log::info!("Request processed", { "duration_ms": 42 });
```
