//! 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
