Empty statements represented by a semicolon ;
are statements that do not perform any operation. They are often the result of a typo or
a misunderstanding of the language syntax. It is a good practice to remove empty statements since they don’t add value and lead to confusion and
errors.
Code examples
Noncompliant code example
fn main() {
let x = 5;
if x > 0 {
println!("x is positive");
}; // Noncompliant
match x {
1 => println!("x is one"),
2 => println!("x is two"),
_ => println!("x is something else"),
}; // Noncompliant
}
Compliant solution
fn main() {
let x = 5;
if x > 0 {
println!("x is positive");
}
match x {
1 => println!("x is one"),
2 => println!("x is two"),
_ => println!("x is something else"),
}
}
