//! # MuIR AST crate
//!
//! This crate provides data structures to allow construct MuIR in Rust code, including:
//!
//! * types
//! * ir
//!   * MuFunction
//!   * MuFunctionVersion
//!     * FunctionContent
//!       * Block
//!         * BlockContent
//!           * TreeNode
//!             * Value
//!             * Instruction
//! * inst
//! * op (operators)
//!
//! Client should not create MuIR via this crate, use API instead.
