Enum.slice/3
defmodule Enum do
def slice(enumerable, start, count)
end
Returns a subset list of the given enumerable
, from start
(zero-based) with count
number of elements if available.
A negative start
can be passed, which means the enumerable is enumerated once and the index is counted from the end.
It returns [] if count
is 0 or if start
is out of bounds.
