Rust has logging integrated into the language at a very low level, and the implementation is very old (from before the language was even self-hosting). With modern Rust, the logging system could be much more robust, implemented in the core library instead of in the language itself. It should be able to do the things you would typically expect from a logging system, in particular providing fine control over which logs are generated and over how they are delivered and displayed.
