Function try_init

pub fn try_init() -> Result<(), SetLoggerError>

Available on crate feature env_logger only.

Attempts to initialize the global logger with an env logger configured to emit tracing events.

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.
