See #95 This branch renames everything from `tokio-trace` to `tracing`. Unlike PR #98, the nursery crates still depend on the crates.io versions of `tokio-trace` and `tokio-trace-core`, but renamed to `tracing`/`tracing-core` in `Cargo.toml`. We can update the nursery crates to depend on local path dependencies in a subsequent PR, as that will require making code changes to the nursery crates. This branch _also_ updates the minimum Rust version to 1.34.0, to the shock and horror of the millions of `tracing` users still on Rust 1.26.0. This was necessary in order to allow renaming crates in `Cargo.toml`, and to resolve that not using the `dyn` keyword is now a warning on nightly.

tracing
Application-level tracing for Rust.
Overview
tracing is a framework for instrumenting Rust programs to collect
structured, event-based diagnostic information. tracing is maintained by the
Tokio project, but does not require the tokio runtime to be used.
Getting Help
First, see if the answer to your question can be found in the API documentation. If the answer is not there, there is an active community in the Tracing Gitter channel. We would be happy to try to answer your question. Last, if that doesn't work, try opening an issue with the question.
Contributing
🎈 Thanks for your help improving the project! We are so happy to have you! We have a contributing guide to help you get involved in the Tracing project.
Project layout
The tracing crate contains the primary instrumentation API, used for
instrumenting libraries and applications to emit trace data. The tracing-core
crate contains the core API primitives on which the rest of tracing is
instrumented. Authors of trace subscribers may depend on tracing-core, which
guarantees a higher level of stability.
Additionally, this repository contains several compatibility and utility
libraries built on top of tracing. Some of these crates are in a pre-release
state, and are less stable than the tracing and tracing-core crates.
The crates included as part of Tracing are:
-
tracing-fmt: A subscriber for formatting and logging trace events. -
tracing-futures: Utilities for instrumentingfutures(unstable). -
tracing-macros: Experimental macros for emitting trace events (unstable). -
tracing-proc-macros: Procedural macro attributes for automatically instrumenting functions (unstable). -
tracing-log: Compatibility with thelogcrate (unstable). -
tracing-env-logger: A subscriber that logs trace events using theenv_loggercrate (unstable). -
tracing-serde: A compatibility layer for serializing trace data withserde(unstable). -
tracing-subscriber: Utilities for subscriber implementations (unstable). -
tracing-tower: Compatibility with thetowerecosystem (unstable). -
tracing-tower-http:towercompatibility for HTTP services (unstable).
