Returns the keywise difference of two maps. So: Only the part of map_a is returned that has keys not in map_b.

Examples:

iex> Tensor.Helper.map_difference(%{a: 1, b: 2, c: 3, d: 4}, %{b: 3, d: 5})
%{a: 1, c: 3}

Returns the keywise difference of two maps. So: Only the part of map_a is returned that has keys also in map_b.

Examples:

iex> Tensor.Helper.map_intersection(%{a: 1, b: 2, c: 3, d: 4}, %{b: 3, d: 5})
%{b: 2, d: 4}

Puts val under map inside a nested map indicated with keys. This is required, as the normal put_in will fail if one of the levels indicated by keys is not initialized to a map yet.

Examples:

iex>put_in_path(%{}, [1,2,3], 4) %{1 => %{2 => %{3 => 4}}}

Swaps the element at position pos_a with the element at position pos_b inside a list.

Examples

iex> swap_elems_in_list([1,2,3,4,5], 1, 3) [1, 4, 3, 2, 5]
