I am trying to iterate over a map, and repeatedly update a struct using each {k, v} pair in the map. But I am having difficulty figuring out how to pass the new/updated struct to the next iteration of the function. So I have something like:

struct = %MyStruct{...}
map = %{key1: value1, key2: value2,...}

def my_func(struct, key, value) do
  struct = # some code that updates the struct using the key and value
  struct # return the new struct
end

and I am trying to do something like:

struct = Enum.each(map, fn {key, value} -> my_func(struct, key, value) end)
{:ok, struct}

Obviously that code does not work, because Enum.each/2 returns :ok, but doesn’t carry the updated struct into the next iteration of the function, and doesn’t return the struct itself. It seems like I need a form of Enum.reduce/3 where the struct acts as the accumulator. How would you approach this?
