Command-Line Rust: A Project-Based Primer for Writing Rust CLIs (pdf)

Description

Rather than focusing on the language as a whole, this guide teaches Rust using a single small, complete, focused program in each chapter. Author Ken Youens-Clark shows you how to start, write, and test each of these programs to create a finished product. You’ll learn how to handle errors in Rust, read and write files, and use regular expressions, Rust types, structs, and more.

Discover how to:

• Use Rust’s standard libraries and data types such as numbers, strings, vectors, structs, Options, and Results to create command-line programs
• Write and test Rust programs and functions
• Read and write files, including stdin, stdout, and stderr
• Document and validate command-line arguments
• Write programs that fail gracefully
• Parse raw and delimited text manually, using regular expressions and Rust crates
• Use and control randomness
