pub fn try_init_timed_custom_env( environment_variable_name: &str ) -> Result<(), SetLoggerError>
Initialized the global logger with a timed pretty env logger, with a custom variable name.
This should be called early in the execution of a Rust program, and the global logger may only be initialized once. Future initialization attempts will return an error.
This function fails to set the global logger if one has already been set.
