adk-telemetry 0.5.0

//! # ADK Telemetry
//!
//! Production-grade observability for ADK using structured logging and distributed tracing.
//!
//! ## Features
//! - Structured logging with `tracing`
//! - OpenTelemetry integration for distributed tracing
//! - OTLP export for observability backends (Jaeger, Datadog, etc.)
//! - Automatic context propagation
//!
//! ## Usage
//!
//! ```rust
//! use adk_telemetry::{init_telemetry, info, instrument};
//!
//! fn main() -> Result<(), adk_telemetry::TelemetryError> {
//!     // Initialize telemetry in your main
//!     init_telemetry("my-service")?;
//!
//!     // Use logging macros
//!     #[instrument]
//!     async fn my_function() {
//!         info!("Function called");
//!     }
//!     Ok(())
//! }
//! ```
