4//! Runtime expression evaluator. Compiles RQL expressions into a small typed tree that the VM can apply over
5//! columns - access, arithmetic, comparison, logical, casts, conversions, lookups, function and routine calls.
6//! Evaluation operates on column buffers wherever possible so a per-row interpreter cost is paid only when an
7//! expression cannot be vectorised.
8//!
9//! This module is the engine-side counterpart to RQL's `expression/` planner module: that crate produces the
10//! expression representation, this one runs it.
