Function tracing_log::env_logger::init

pub fn init()

This is supported on crate feature env_logger only.

Initializes 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.

Panics

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