Vectors

A vector is a native data structure of Rune which is a dynamic list of values. A vector isn't typed, and can store any Rune values.

pub fn main() {
    let values = ["Hello", 42];

    println!("{}", values[0]);
    println!("{}", values.1); // items in vectors can be accessed like tuple fields.

    for v in values {
        println!("{}", v);
    }
}

$> cargo run --bin rune -- run scripts/book/vectors/vectors.rn
Hello
42
Hello

== () (5.0674ms)

As you can see, you can iterate over a vector because it implements the iterator protocol. It is also possible to create and use an iterator manually using Vec::iter, giving you more control over it.

pub fn main() {
    let values = ["Hello", 42];

    for v in values.iter().rev() {
        println!("{}", v);
    }
}

$> cargo run --bin rune -- run scripts/book/vectors/vectors_rev.rn
