vendor/tabled/examples/builder_index.rs

   1 //! This example demonstrates evolving the standard [`Builder`] to an [`IndexBuilder`],
   2 //! and then manipulating the constructing table with a newly prepended index column.
   3 //!
   4 //! * An [`IndexBuilder`] is capable of several useful manipulations, including:
   5 //!     * Giving the new index column a name
   6 //!     * Transposing the index column around a table
   7 //!     * Choosing a location for the new index column besides 0; the default
   8 //!
   9 //! * Note that like with any builder pattern the [`IndexBuilder::build()`] function
  10 //! is necessary to produce a displayable [`Table`].
