Function init_with_level

pub fn init_with_level(level: Level) -> Result<(), SetLoggerError>

Register slog-stdlog as log backend. Pass a log::Level to do the log filter explicitly.

This will pass all logging statements crated with log crate to current slog-scope::logger().

    let drain = slog_async::Async::new(drain).build().fuse();
    let logger = slog::Logger::root(drain, slog_o!("version" => env!("CARGO_PKG_VERSION")));

    let _scope_guard = slog_scope::set_global_logger(logger);
    let _log_guard = slog_stdlog::init_with_level(log::Level::Error).unwrap();
