Stream.zip_with
zip_with, go back to Stream module for more information.
Specs
zip_with(enumerables, (Enumerable.t() -> term())) :: Enumerable.t() when enumerables: [Enumerable.t()] | Enumerable.t()
Lazily zips corresponding elements from a finite collection of enumerables into a new
enumerable, transforming them with the zip_fun function as it goes.
The first element from each of the enums in enumerables will be put into a list which is then passed to
the 1-arity zip_fun function. Then, the second elements from each of the enums are put into a list and passed to
zip_fun, and so on until any one of the enums in enumerables completes.
Returns a new enumerable with the results of calling zip_fun.
Examples
iex> concat = Stream.concat(1..3, 4..6)
iex> Stream.zip_with([concat, concat], fn [a, b] -> a + b end) |> Enum.to_list()
[2, 4, 6, 8, 10, 12]
iex> concat = Stream.concat(1..3, 4..6)
iex> Stream.zip_with([concat, concat, 1..3], fn [a, b, c] -> a + b + c end) |> Enum.to_list()
[3, 6, 9]Specs
zip_with(Enumerable.t(), Enumerable.t(), (term(), term() -> term())) :: Enumerable.t()
Lazily zips corresponding elements from two enumerables into a new one, transforming them with
the zip_fun function as it goes.
The zip_fun will be called with the first element from enumerable1 and the first
element from enumerable2, then with the second element from each, and so on until
either one of the enumerables completes.
Examples
iex> concat = Stream.concat(1..3, 4..6)
iex> Stream.zip_with(concat, concat, fn a, b -> a + b end) |> Enum.to_list()
[2, 4, 6, 8, 10, 12]
