Module cast 

Structs

CastFunction

SQL CAST(expr AS type).

Enums

CastTarget

The set of target types CAST supports. We deliberately collapse SQL’s large “zoo” of character/numeric types down to the handful of types our engine actually stores in DataValue. This keeps CAST close to DuckDB’s observable behaviour without dragging in fixed-width CHAR, DECIMAL precision, etc.

Functions

cast_value

Coerce a value to the requested target type. Errors describe why a value could not be represented; callers decide whether that error is fatal (CAST) or should become NULL (TRY_CAST). NULL always casts to NULL.
