Crate zlayer_observability 

ZLayer Observability - Logging, Tracing, and Metrics

Provides unified observability infrastructure:

• Structured logging with JSON/pretty formats
• OpenTelemetry distributed tracing
• Prometheus metrics exposition

Quick Start

use zlayer_observability::{init_observability, ObservabilityConfig};

#[tokio::main]
async fn main() {
    let config = ObservabilityConfig::default();
    let _guards = init_observability(&config).expect("Failed to init observability");

    tracing::info!("Application started");
}
