Function init_builtin_logger 

pub fn init_builtin_logger()

Initializes the builtin cmd_lib_cf logger

This is to make examples in this library work, and users should usually use a real logger instead. When being used, it should be called early in the main() function. Default log level is set to debug.

Panics

This function will panic if it is called more than once, or if another library has already initialized a global logger.
