A.Vector.foldr
You're seeing just the function
foldr
, go back to A.Vector module for more information.
Specs
Folds (reduces) the given vector
from the right with the function fun
.
Requires an accumulator acc
.
Unlike linked lists, this is as efficient as foldl/3
. This can typically save a call
to Enum.reverse/1
on the result when building a list.
Runs in linear time.
Examples
iex> A.Vector.new(1..10) |> A.Vector.foldr(0, &+/2)

iex> A.Vector.new(1..10) |> A.Vector.foldr([], & [&1 | &2])
