1//! Reading, writing, and manipulating bytes.
2//!
3//! In this module, we use the following type shorthands:
4//! - R is the [`Reader`]: for dd, this is either [`Stdin`][std::io::StdinLock]
5//!   or a
6//! [`File`][std::fs::File]
7//! - W is the [`Writer`]: for dd, this is either   [std::io::StdoutLock]
8//! or a [`File`][std::fs::File]
9//! - C is a [`ConvertSlice`], which modifies a slice of bytes in-place. During
10//!   operation, this is always a [`Converter`]
11//! - E is the [`ErrHandler`]. During operation, this is  [std::io::StderrLock].
