Sorts the enumerable and removes duplicates.
It is more efficient than calling Enum.sort/1 followed by Enum.uniq/1,
and slightly faster than Enum.sort/1 followed by Enum.dedup/1.
Examples
iex> A.Enum.sort_uniq([1, 4, 2, 2, 3, 1, 4, 3])
[1, 2, 3, 4]Sorts the enumerable by the given function and removes duplicates.
See Enum.sort/2 for more details about how the second parameter works.
Examples
iex> A.Enum.sort_uniq([1, 4, 2, 2, 3, 1, 4, 3], &(&1 >= &2))
[4, 3, 2, 1]
iex> A.Enum.sort_uniq([1, 4, 2, 2, 3, 1, 4, 3], :asc)
[1, 2, 3, 4]
iex> A.Enum.sort_uniq([1, 4, 2, 2, 3, 1, 4, 3], :desc)
[4, 3, 2, 1]
iex> dates = [~D[2019-01-01], ~D[2020-03-02], ~D[2019-01-01], ~D[2020-03-02]]
iex> A.Enum.sort_uniq(dates, {:desc, Date})
[~D[2020-03-02], ~D[2019-01-01]]
