   9 //! Convenience re-export of common members

  11 //! Like the standard library's prelude, this module simplifies importing of
  12 //! common items. Unlike the standard prelude, the contents of this module must
  13 //! be imported manually:
  14 //!
  15 //! ```
  16 //! use rand::prelude::*;
  17 //! # let mut r = StdRng::from_rng(thread_rng()).unwrap();
  18 //! # let _: f32 = r.gen();
  19 //! ```
