Expand description
Array validity and nullability behavior, used by arrays and compute functions.
Validity describes which rows are logically present without forcing every array to carry a
materialized boolean bitmap. Constant states (NonNullable, AllValid, AllInvalid) are cheap
to clone and inspect. Validity::Array may itself be encoded or lazy, so APIs that need exact
per-row answers take an ExecutionCtx and execute the validity array as needed.
