* Converter.apply (like Converter.convert) is capable of accepting null inputs. However, a
 * supertype of `Function<A, B>` turns out to be massively more useful to callers in practice: They
 * want their output to be non-null in operations like `stream.map(myConverter)`, and we can
 * guarantee that as long as we also require the input type to be non-null[*] (which is a
 * requirement that existing callers already fulfill).

You already created an API that:

* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`.
* Both _paths_ take `GET` operations (also known as HTTP _methods_).
* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`.
* The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`.

        // Full lease for read/write/handle operations
        if (hasWriteAccess || hasDeleteAccess) {
            return Smb2LeaseState.SMB2_LEASE_FULL; // Read + Write + Handle
        }
        // Read + Handle for read operations
        else if (hasReadAccess) {
            return Smb2LeaseState.SMB2_LEASE_READ_HANDLE; // Read + Handle
        }

    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.

what the toolchain actually generates for that operation might
not be a move instruction at all, perhaps a clear or load.
Or it might correspond exactly to the machine instruction with that name.
In general, machine-specific operations tend to appear as themselves, while more general concepts like
memory move and subroutine call and return are more abstract.
The details vary with architecture, and we apologize for the imprecision; the situation is not well-defined.
