Let's say that now the file `main.py` with your **FastAPI** app has some other **path operations**.

It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

// ARMMRCOffset implements the peculiar encoding of the MRC and MCR instructions.

If both types are bound type parameters, they unify per the given
matching modes if:

<ul>
<li>
	Both type parameters are identical.
</li>
<li>
	At most one of the type parameters has a known type argument.
	In this case, the type parameters are <i>joined</i>:
	they both stand for the same type argument.

A note about ZIP64:

To be backwards compatible the FileHeader has both 32 and 64 bit Size
fields. The 64 bit fields will always contain the correct value and
for normal archives both fields will be the same. For files requiring
the ZIP64 format the 32 bit fields will be 0xffffffff and the 64 bit
fields must be used instead.

            //
            // So that is why we cancel only in the case of CAS success.
            taskFuture.cancel(false);
          }
        };
    // Adding the listener to both futures guarantees that newFuture will always be set. Adding to
    // taskFuture guarantees completion if the callable is invoked, and adding to outputFuture
    // propagates cancellation if the callable has not yet been invoked.
