Walkthrough

The change updates the internal validation logic in the ActiveOperation constructor to ensure that the local_descriptors and remote_descriptors parameters are both of the same type (either both lists or both single descriptors) and that their sizes match. Additional checks provide detailed error messages for mismatches.

Changes

File(s) Change Summary
examples/multimodal/connect/init.py Refactored and extended validation logic for local_descriptors and remote_descriptors in ActiveOperation.__init__ to include type and size consistency checks with detailed errors.

Poem

In the warren of code, checks now abound,
Descriptors in pairs, their sizes are found.
No mismatched lists, no confusing cries,
Just clear validation—no more surprise!
🐇✨

211-213: Boolean-comparison trick slightly harms readability

isinstance(local_descriptors, list) != isinstance(remote_descriptors, list) is compact but forces the reader to mentally parse a boolean XOR.
An explicit formulation communicates intent faster:

if (isinstance(local_descriptors, list) and not isinstance(remote_descriptors, list)) or \
   (isinstance(remote_descriptors, list) and not isinstance(local_descriptors, list)):
    raise ValueError(...)

Not a blocker, but consider the explicit form for long-term maintainability.


214-219: Use zip to avoid redundant indexing & repeated len() calls

Iterating with indices adds noise and performs an unnecessary len() on every loop:

-for i in range(len(local_descriptors)):
-    if local_descriptors[i].size != remote_descriptors[i].size:
-        raise ValueError(
-            f"Descriptor length mismatch: `local_descriptors` and `remote_descriptors` "
-            f"descriptor at {i} must have the same size. "
-            f"{local_descriptors[i].size} != {remote_descriptors[i].size}."
-        )
+for i, (l_desc, r_desc) in enumerate(zip(local_descriptors, remote_descriptors)):
+    if l_desc.size != r_desc.size:
+        raise ValueError(
+            f"Descriptor size mismatch at index {i}: {l_desc.size} != {r_desc.size}."
+        )

Cleaner, slightly faster, and less error-prone.


220-221: Indentation appears deeper than required

The raise inside the elif block is indented two levels instead of one.
Although Python doesn’t mind the extra spaces, uneven indentation can trip diff tools and future reviewers.

-        elif (...) and local_descriptors.size != remote_descriptors.size:
-                raise ValueError(...)
+        elif (...) and local_descriptors.size != remote_descriptors.size:
+            raise ValueError(...)

Quick tidy-up keeps the style consistent with the surrounding blocks.
