[ty] Avoid AST load for callable description names by charliermarsh · Pull Request #25728 · astral-sh/ruff (original) (raw)

Summary

CallableDescription loaded the parsed module only to read the enclosing class name when formatting Class.method for function and bound-method diagnostics.

This now recovers the enclosing class from the semantic index and formats the name from the original class type metadata, avoiding that direct AST node lookup while preserving the same display text.
