rust-tracing-subscriber 0.2.15 Implement and compose tracing subscribers

This package provides utilities for implementing and composing tracing subscribers.

Tracing is a framework for instrumenting Rust programs to collect scoped, structured, and async-aware diagnostics. The Subscriber trait represents the functionality necessary to collect this trace data. This crate contains tools for composing subscribers out of smaller units of behaviour, and batteries-included implementations of common subscriber functionality.

Tracing-subscriber is intended for use by both Subscriber authors and application authors using tracing to instrument their applications.
