In Rust, there are two types of comments:
1. //: Used for single-line comments.
2. /* */: Used for multiline comments.
Here are some examples:
// This is a single-line comment.
fn main() {
// This is a comment on a line with code.
println!("Hello, world!"); // This is another comment on the same line as code.
}
/*
This is a
multiline comment
that spans multiple lines.
*/
// The below code contains commented out code that is not executed:
/*
fn unused_function() {
println!("This function is not used.");
}
*/
It's always a good practice to add comments within your code to explain the functionality of the code to yourself or others who may read your code in the future.
