//! Collection of process I/O handlers.
//!
//! The I/O handler contains all the I/O logic. It takes input from
//! the coroutine, processes the requested I/O, then puts the output
//! back inside the coroutine.
//!
//! If you miss a handler matching your requirements, you can easily
//! implement your own by taking example on the existing ones. PRs are
//! welcomed!
