SQL Parser

This module provides a complete SQL parser for Stoolap, including:

  • Lexer - Tokenizer for SQL input
  • Parser - Parser that builds AST from tokens
  • ast - Abstract Syntax Tree types
  • token - Token types
  • error - Parser error types

§Example

use stoolap::parser::{parse_sql, Statement};

let sql = "SELECT * FROM users WHERE id = 1";
let statements = parse_sql(sql).unwrap();
assert_eq!(statements.len(), 1);
