Rust slices

Table of contents

Slices are a dynamically sized view into a sequence. Therefore, you can have a slice which references an array or a vector and treat them the same. –

fn main() {
    let numbers = [10, 20, 30, 40, 50];
    let subset_1 = &numbers[1..3];
    let subset_2 = &numbers[1..=3];
    println!("subset_1");
    for n in subset_1 {
        println!("{n}");
    }
    println!("subset_2");
    for n in subset_2 {
        println!("{n}");
    }
    println!("numbers_2");
    let numbers_2: Vec<u8> = (1..5).collect();
    for n in numbers_2 {
        println!("{n}");
    }
}

Possible output

subset_1
20
30
subset_2
20
30
40
numbers_2
1
2
3
4
