//! SQL Parser for Rust
//!
//! This crate provides an ANSI:SQL 2011 lexer and parser that can parse SQL
//! into an Abstract Syntax Tree (AST). See the [sqlparser crates.io page]
//! for more information.
//!
//! See [`Parser::parse_sql`](crate::parser::Parser::parse_sql) and
//! [`Parser::new`](crate::parser::Parser::new) for the Parsing API
//! and the [`ast`](crate::ast) crate for the AST structure.
//!
//! Example:
//!
//! ```
//! use sqlparser::dialect::GenericDialect;
//! use sqlparser::parser::Parser;
//!
//! let dialect = GenericDialect {}; // or AnsiDialect
//!
//! let sql = "SELECT a, b, 123, myfunc(b) \
//!            FROM table_1 \
//!            WHERE a > b AND b < 100 \
//!            ORDER BY a DESC, b";
//!
//! let ast = Parser::parse_sql(&dialect, sql).unwrap();
//!
//! println!("AST: {:?}", ast);
//! ```
