One Reply to "A deep dive into Rust iterators and closures"

  1. Is logrocket a content farm? It increasingly pops up when searching for Rust stuff, but it seems to be mostly basic material with links to other texts on the same site.
    The click-bait title of this article is misleading. This is not a deep dive, at best it is a superficial introduction. It also contains errors.

    1. Closures does not “create a reference to the entities in its scope”, this doesn’t compile:
    “`
    fn main() {
    let foo: String = String::from(“hello”);
    let c = |x| {
    let y: &String = x;
    println!(“{}”, y);
    };
    c(foo);
    }
    “`

    2. It’s not true that one “cannot iterate through a set of values (arrays, vectors, maps) in Rust using loops”:
    “`
    fn main() {
    let vec = vec![1, 2, 3];
    for i in 0..3 {
    println!(“{:?}”, vec.get(i));
    }
    }
    “`
