//! An abstract syntax tree for SQL queries.
//!
//! The ast module handles everything related building abstract SQL queries
//! without going into database-level specifics. Everything related to the
//! actual query building is in the [visitor](../visitor/index.html) module.
//!
//! For prelude, all important imports are in `quaint::ast::*`.
