Chapter 10: Working with Device I/O

In Chapter 6, Working with Files and Directories in Rust, we covered the details of how to perform file I/O operations (such as reading and writing to files) using the Rust Standard Library. In Unix-like operating systems, a file is an abstraction that is used to work not only with regular disk files (which are used to store data) but also with several types of devices that are connected to a machine. In this chapter, we will look at the features of the Rust Standard Library that enable us to perform reads and writes to any type of device (also called device I/O) in Rust. Device I/O is an essential aspect of system programming to monitor and control various types of devices attached to a computer, such as keyboards, USB cameras, printers, and sound cards. You may be curious to know what support Rust provides to a system programmer to handle all these different types of devices. We'll answer this question as we go through the chapter.
