pub fn usage_masks(m: &Module) -> Result<[Vec<Option<u8>>; 3]>Expand description
The usage mask of each signature element (tag 3 of the element’s trailing tag list: the components of the element
the program reads or writes, bit 0 the element’s first component, so a scalar packed into component w states 1,
not 8), in the order of elements’ inputs and outputs and patch_elements; None for an element whose trailing tag list is absent or has no tag 3. In the stock programs
the only tag the lists hold is 3 (138,044 of 145,462 elements of skate.’s, 459,288 of 545,303 of Elden Ring’s);
any other tag is ignored (see element_tags for them).
