//! Converts between arrays and Apache Arrow arrays.
//!
//! This file acts as a template file for conversion code between
//! arrays and different version of Apache Arrow.
//!
//! The conversion logic will be implemented for the arrow version specified in the outer mod by
//! `super::arrow_xxx`, such as `super::arrow_array`.
//!
//! When we want to implement the conversion logic for an arrow version, we first
//! create a new mod file, and rename the corresponding arrow package name to `arrow_xxx`
//! using the `use` clause, and then declare a sub-mod and set its file path with attribute
//! `#[path = "./arrow_impl.rs"]` so that the code in this template file can be embedded to
//! the new mod file, and the conversion logic can be implemented for the corresponding arrow
//! version.
//!
//! Example can be seen in `arrow_default.rs`, which is also as followed:
//! ```ignore
//! use {arrow_array, arrow_buffer, arrow_cast, arrow_schema};
//!
//! #[allow(clippy::duplicate_mod)]
//! #[path = "./arrow_impl.rs"]
//! mod arrow_impl;
//! ```

// Is this a bug? Why do we have these lints?
