slog-rs - The Logging for Rust
You might consider using
It's been a while since
slog was created and it served
Rust community well all this time. It remains a stable, featureful
and battle-tested library, used in many important projects.
In last few years,
another ecosystem for Rust was
created with similar features and a very good support for debugging
and already larger dev team and community.
Please check tracing and see if it is more suitable for your use-case. It seems that it is already a go-to logging/tracing solution for Rust.
Reasons you might want to stick with
asyncsupport doesn't benefit you
- you consider mature, stable code & API a plus
- it has some features that
- great performance (I have NOT done any comparison, but
slog's performance is very good).
Introduction (please read)
slog is an ecosystem of reusable components for structured, extensible,
composable and contextual logging for Rust.
The ambition is to be The Logging Library for Rust.
slog should accommodate a
variety of logging features and requirements. If there is a feature that you
need and standard
log crate is missing,
slog should have it.
This power comes with a little steeper learning curve, so if you experience any problems, please join slog-rs gitter channel to get up to speed. If you'd like to take a quick, convenient route, consider using sloggers wrapper library.
While the code is reliable, the documentation sometimes could use an improvement. Please report all issues and ideas.
Features & technical documentation
Most of the interesting documentation is auto-generated and hosted on https://docs.rs.
Go to docs.rs/slog to read about features and APIs (examples included).
slog is just a core, and the actual functionality is inside
many feature crates. To name a few:
- slog-term for terminal output
- slog-async for asynchronous logging
- slog-json for logging JSON
- slog-syslog for logging to syslog
- sloggers for convenience methods (note: 3rd-party library)
Terminal output example
slog-term is only one of many
slog features - useful showcase,
multi-platform, and featuring eg. automatic TTY detection and colors.
See following screenshot: same output in both compact and full output mode.

Any particular repositories under slog ecosystem might be created, controlled, maintained by other entities with various levels of autonomy. Lets work together toward a common goal in a respectful and welcoming atmosphere!
To help with the maintained, the ownership of this crate is potentially shared between multiple developers. It is recommended to always use cargo-crev to verify the trustworthiness of each of your dependencies, including this one.
