Let's say I have a struct like this:

  struct MyType {
    address token;
    uint256 amount;

  function hello(MyType[]) external {

What would my function signature (and, therefore, function selector) look like?

You'd wrap the primative types in parenthesis and put brackets after them.

For example:

cast sig "hello((address,uint256)[])"
