#![deny(warnings, missing_docs)]

//! This crate provides:
//! - `TelemetryLayer`, a generic tracing layer that handles publishing spans and events to arbitrary backends
//! - Utilities for implementing distributed tracing for arbitrary backends
//!
//! As a tracing layer, `TelemetryLayer` can be composed with other layers to provide stdout logging, filtering, etc.
//!
//! This crate is primarily intended to be used by people implementing their own backends.
//! A concrete implementation using honeycomb.io as a backend is available in the [`tracing-honeycomb` crate](https://crates.io/crates/tracing-honeycomb).
