//! This crate automatically generates the definition of the `Visit`,
//! `VisitMut`, and `Fold` traits in `syn` based on the `syn` source. It
//! discovers structs and enums declared with the `ast_*` macros and generates
//! the functions for those types.
//!
//! It makes a few assumptions about the target crate:
//! 1. All structs which are discovered must be re-exported in the root of the
//!    crate, even if they were declared in a submodule.
//! 2. This code cannot discover submodules which are located in subdirectories
//!    - only submodules located in the same directory.
//! 3. The path to `syn` is hardcoded.
