Web Reference: We define a function in Rust by entering fn followed by a function name and a set of parentheses. The curly brackets tell the compiler where the function body begins and ends. Functions are groups of one or more lines of reusable code to perform a specific task. In this tutorial, you will learn about the Rust functions with the help of examples.
