pub fn init_with_env() -> Result<(), SetLoggerError>
Expand description

Initialise the logger with the RUST_LOG environment variable.

Log messages will be filtered based on the RUST_LOG environment variable.

This will use the default level (LevelFilter::Trace) if the RUST_LOG environment variable is not set or can’t be parsed as a standard log level (see LevelFilter::from_str and [log::LOG_LEVEL_NAMES] for valid names).
