Best way to handle structure with different data

[red tinsel]

I'm adding a bunch of different actions to a queue which will then need to be processed. Each action will have different data which it comes with.
My initial thoughts on how to do this would be a pointer to whatever data structure necessary through a struct, I can determine what structure that is via the action enum and cast appropriately.

Is there a better, cleaner way to do it than this though?

const ActionInfo = {
  action: Action,
  value: Pointer // Will point to a different structure depending on the action
}

const Action = enum {
  ...
}

You might use a tagged union for that https://ziglang.org/documentation/master/#Tagged-union

const Action = union(enum) {
  one: *One,
  two: *Two,
};

if you know all the different types
