//! APIs to read Arrow's IPC format.
//!
//! The two important structs here are the [`FileReader`](reader::FileReader),
//! which provides arbitrary access to any of its messages, and the
//! [`StreamReader`](stream::StreamReader), which only supports reading
//! data in the order it was written in.
