rustHow to pass a Rust slice as a parameter?

Passing a Rust slice as a parameter is done by using the &[T] syntax. This syntax indicates that a slice of type T is being passed as a parameter.

Example

fn print_slice(slice: &[i32]) {
    println!("{:?}", slice);
}

fn main() {
    let arr = [1, 2, 3];
    print_slice(&arr);
}

Output example

[1, 2, 3]

Code explanation

• fn print_slice(slice: &[i32]): This is the function definition, which takes a slice of type i32 as a parameter.
• let arr = [1, 2, 3]: This is the array that will be passed as a parameter.
• print_slice(&arr): This is the function call, which passes the array as a parameter.
