Crate fsqlite_ast 

SQL Abstract Syntax Tree node types for FrankenSQLite.

This module defines the complete AST type hierarchy for the SQLite SQL dialect. Every SQL statement parsed by fsqlite-parser produces a tree of these nodes. All expression nodes carry a Span for error reporting.

Reference: §10.3–10.4 of the FrankenSQLite specification.
