  11 //! The core prelude
  12 //!
  13 //! This module is intended for users of libcore which do not link to libstd as
  14 //! well. This module is not imported by default, but using the entire contents
  15 //! of this module will provide all of the useful traits and types in libcore
  16 //! that one would expect from the standard library as well.
  17 //!
  18 //! There is no method to automatically inject this prelude, and this prelude is
  19 //! a subset of the standard library's prelude.
  20 //!
  21 //! # Example
  22 //!
  23 //! ```ignore
  24 //! use core::prelude::*;
  25 //! ```
