Optimize extraction functions and improve semantic clarity in can?#45
Conversation
This commit makes two improvements to the indexed implementation:
1. Performance optimization: Replace destructuring with direct nth access
- extract-resource-id-from-rel-tuple-datom now uses nth for speed
- extract-subject-id-from-reverse-rel-tuple-datom now uses nth for speed
- Added docstrings documenting tuple formats for clarity
2. Semantic clarity: Use correct extraction function for reverse lookups
- can? function now uses extract-subject-id-from-reverse-rel-tuple-datom
for reverse index lookups (lines 258 and 275)
- While both functions extract from position 4, using the semantically
correct function makes the code intent clearer and more maintainable
Note: Both tuple formats have the desired eid at position 4, so this
change improves code clarity without fixing an actual bug.
