//! This crate provides:

//!

//! 1. A SQL parser, [`DFParser`], that translates SQL query text into

//! an abstract syntax tree (AST), [`Statement`].

//!

//! 2. A SQL query planner [`SqlToRel`] that creates [`LogicalPlan`]s

//! from [`Statement`]s.

//!

//! 3. A SQL [`unparser`] that converts [`Expr`]s and [`LogicalPlan`]s

//! into SQL query text.

//!

//! [`DFParser`]: parser::DFParser

//! [`Statement`]: parser::Statement

//! [`SqlToRel`]: planner::SqlToRel

//! [`LogicalPlan`]: datafusion_expr::logical_plan::LogicalPlan

//! [`Expr`]: datafusion_expr::expr::Expr
