What is a comment?
In computer programming, comments are lines of text used to describe the purpose of code. For example,
// entry point of the program
fn main() {
// print text on the screen
println!("Hello, World!");Types of Comments
There are two important types of comments in Rust:
//- Line Comment/*...*/- Block Comment
/*
* This is another type of comment, a block comment. In general,
* line comments are the recommended comment style. But block comments
* are extremely useful for temporarily disabling chunks of code.
* /* Block comments can be /* nested, */ */ so it takes only a few
* keystrokes to comment out everything in this main() function.
* /*/*/* Try it yourself! */*/*/
*/
Note: Rustatian prefer line comments over block comments.
