PatchMarker(
    index: int ,
)-> None

Stands for a patch handed to an operation as an argument.

A patch argument is an input, not a parameter. index is its place in the operation’s inputs, so which argument each input filled is part of the operation: where(cond=a, other=b) is not where(cond=b, other=a).
