//! Columnar data model used by the engine and every consumer of query results.
//!
//! A column is a typed, possibly-nullable, possibly-dictionary-encoded buffer of values plus statistics, encoding
//! metadata, and a none-bitmap.
//!
//! Invariant: a column's `RowMask` and `NoneBitmap` are always exactly aligned to its logical row count. Operations
//! that grow or shrink the buffer must update the mask and bitmap atomically with respect to consumers; an off-by-one
//! between length and mask silently produces wrong results in filter and aggregation paths.
