Cache the union of two types as a tracked function by AlexWaygood · Pull Request #23565 · astral-sh/ruff

AlexWaygood · 2026-02-25T19:44:59Z

The same as #23547, but for unions rather than intersections. Similar to #23547, this appears to bring across-the-board performance improvements without significant memory-usage increases.

Similar to #23547 which added `IntersectionType::from_two_elements`, this adds a cached `UnionType::from_two_elements` method that wraps the union of exactly two types in a `#[salsa::tracked]` function. This enables Salsa to memoize two-element union constructions, which are by far the most common case, avoiding redundant work on repeated queries. All non-test callsites of `UnionType::from_elements` that pass exactly two elements have been updated to use the new method. https://claude.ai/code/session_01B8moosqrkcptHVjNT7LvrU
