How to skip forward multiple times in a loop?-CodePudding

I have this code in Rust:

for ch in string.chars() {
    if ch == 't' {
        // skip forward 5 places in the string
    }
}

In C, I believe you can just do this:

for (int i = 0; i < strlen(string);   i) {
    if (string[i] == 't') {
        i  = 4;
        continue;
    }
}

How would you implement this in Rust? Thanks.

CodePudding user response：

Since string.chars() gives us an iterator, we can use that to create our own loop that gives us controls about the iterator:

let string = "Hello World!";
let mut iter = string.chars();

while let Some(ch) = iter.next() {
    if ch == 'e' {
        println!("Skipping");
        iter.nth(5);
        continue;
    }
    println!("{}", ch);
}

Will output:

H
Skipping
r
l
d
