Macro stack 

macro_rules! stack {
    ($($elem:expr),* $(,)?) => { ... };
}

Creates a Vec<u64> for stack inputs where the first element will be on top of the stack.

This macro handles the reversal required by StackInputs::try_from_ints, which reverses its input internally. With this macro, you can specify stack inputs in intuitive order.

Example

// Stack will be [a, b, c, d, ...] with 'a' at position 0 (top)
let inputs = stack![a, b, c, d];
let test = build_op_test!("some_op", &inputs);

Word Helper

To add a Word to the stack with word[0] on top, use the word helper:

// Stack will be [w[0], w[1], w[2], w[3], ...] with w[0] on top
let inputs = stack![word(my_word), other_value];
