Function env_logger::try_init_from_env

pub fn try_init_from_env(env: &str) -> Result<(), SetLoggerError>

Attempts to initialize the global logger with an env logger from the given environment variable.

This should be called early in the execution of a Rust program. Any log events that occur before initialization will be ignored.

Errors

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