Functions
Calls the given fun with each element in the two collections pairwise, meaning, fun is first called with
the first element in a as the first argument to fun and the first element in b as the second
argument to fun. Then it is called with the second element in each list as the first and second
arguments to fun respectively, and so on.
Calls the given mod / fun with each element in the two collections pairwise, meaning, the mod / fun is
first called with the first element in a as the first argument to the function described by the
mod / fun, and the first element in b as the second argument to the function described by
mod / fun. Then it is called with the second element in each list as the first and second
arguments respectively and so on down the collection.
Calls the given mod / fun / args with each element in the two collections pairwise, meaning,
the mod / fun / args is first called with the first element in a as the first argument to
the function described by the mod / fun / args, and the first element in b as the second
argument to the function described by the mod / fun / args, and with the args added as
the rest of the args for the mod / fun. Then it is called with the second element in each list
as the first and second arguments respectively and so on down the collection.

apply(a, b, fun) View Source
Calls the given fun with each element in the two collections pairwise, meaning, fun is first called with
the first element in a as the first argument to fun and the first element in b as the second
argument to fun. Then it is called with the second element in each list as the first and second
arguments to fun respectively, and so on.
Below is an example of what the function returns if we were to implement it for lists:
Examples
iex> Zip.apply([5], [2], fn a, b -> a + b end)
[7]
iex> Zip.apply([5], [2], fn a, b -> a * b end)
[10]apply(a, b, mod, fun) View Source
Calls the given mod / fun with each element in the two collections pairwise, meaning, the mod / fun is
first called with the first element in a as the first argument to the function described by the
mod / fun, and the first element in b as the second argument to the function described by
mod / fun. Then it is called with the second element in each list as the first and second
arguments respectively and so on down the collection.
Below is an example of what the function returns if we were to implement it for lists:
Examples
iex> Zip.apply([[1, 2], [3, 4]], [7, 7], Enum, :intersperse)
[[1, 7, 2], [3, 7, 4]]
iex> Zip.apply([5], [2], Kernel, :+)
[7]apply(a, b, mod, fun, args) View Source
Calls the given mod / fun / args with each element in the two collections pairwise, meaning,
the mod / fun / args is first called with the first element in a as the first argument to
the function described by the mod / fun / args, and the first element in b as the second
argument to the function described by the mod / fun / args, and with the args added as
the rest of the args for the mod / fun. Then it is called with the second element in each list
as the first and second arguments respectively and so on down the collection.
Below is an example of what the function returns if we were to implement it for lists:
Examples
iex> Zip.apply([[1, 2, 3, 4], [1, 2, 3, 4]], [2, 3], Enum, :map_every, [fn x -> x * 10 end])
[[10, 2, 30, 4], [10, 2, 3, 40]]
iex> Zip.apply([["X","X","X","X"], ["O", "O", "O", "O"]], [1, 2], Enum, :map_every, [fn _ -> "A" end])
[["A", "A", "A", "A"], ["A", "O", "A", "O"]]
