Module sql_types 

SQL data type classification helpers shared across SQL-facing crates.

This module centralizes the mapping from sqlparser data types to the compact families our runtime, loader tooling, and planner adapters care about. Keeping the mapping in one place avoids duplicating large match statements every time a new SQL type lands, and it makes downstream crates independent of the full sqlparser enum surface.

Enums

SqlTypeFamily

Reduced set of SQL type families that matter for literal conversion and row-shaping utilities.

Functions

classify_sql_data_type

Classify a sqlparser DataType into one of the planner-friendly families.
