//! Custom configuration example.

//! Shows how to use [`Telemetry::builder`] to configure the service name,
//! version, deployment environment, trace sampler, metrics, logs, and the
//! shutdown timeout.
//!
//! Run with:
//! ```text
//! OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317 cargo run --example custom_config
//! ```
