Summary
Provides comprehensive analysis of value vs pointer receiver patterns across the langchaingo codebase in response to GitHub discussion #94.
Analysis Results
Findings:
Key Issues Identified
1. Mixed Receiver Types (Critical)
Types like , , \ inconsistently mix value and pointer receivers, leading to:
2. Large Structs with Value Receivers
Types like \ (9 fields) and \ (4 fields) use value receivers, causing unnecessary copying.
