Summary
In this chapter, we reviewed the foundational concepts of device management in Unix/Linux. We looked at how to do buffered reads and writes using the std::io module. We then learned how to interact with the standard input, standard output, and standard error streams of a process. We also saw how to chain readers together and use iterators for reading from devices. We then looked at the error handling features with the std::io module. We concluded with a project to detect the list of connected USB devices and printed out the details of each USB device both to the terminal and to an output file.
The Rust Standard Library provides a clean layer of abstraction for doing I/O operations on any type of device. This encourages the Rust ecosystem to implement these standard interfaces for any type of device, enabling Rust system programmers to interact with different devices in a uniform manner. Continuing on the topic of I/O, in the next chapter, we will learn how to do network...
