Module lv 

Logging

Does not require any feature flag

The logging macros (debug, info, trace, warn, error) are re-exported from the log crate and are used as cu::debug!, cu::info!, etc. This means your log statements are integrated into the log infrastructure when you use cu in a library.

Additionally, the cu::fmtand! and cu::panicand! macros allow you to log a message in additional to format!/panic!.

When the cli feature is enabled, you also get log integration with CLI flags and other terminal-printing features. See Command Line Interface

cu::lv shorthands should be used within this library (for example cu::lv::D for debug). You can also call .into() to convert it to log::Level. Additionally cu::lv::LogLevel is a re-export of log::Level.
