Expand description
Initialize Rust’s env logger.
The Rust logger reads the desired log level from the RUST_LOG
environment variable. If this
isn’t set, the provided default is used. If a default fallback isn’t provided to this function,
we fall back to "info"
.
A more robust logging config might configure on a per-component basis, eg.
"tokio_reactor=warn,hyper=info,debug"
. You can read more in the log
and env_logger
