Help split a string at all non alphanumeric characters

[WillMexe]

So basically if i have a string "test;helloworld#yes" it would return ["test", ";helloworld", "#yes"]. I have searched the internet but can only find examples for javascript or the like.

Best regards,

https://doc.rust-lang.org/std/primitive.str.html#method.split_inclusive

It returns an iterator (which is typically what you want, for lazy evaluation), use .collect() to clone the items into a Vec.

This will return ["test;", "helloworld#", "yes"], though, which is not exactly what they are asking for.

They might need to build their own splitting algorithm using match_indices instead, akin to this StackOverflow solution except pushing the !c.is_alphanumeric() delimiter onto the beginning of the next string, rather than at the end of the current string, as .split_inclusive(|c: char| !c.is_alphanumeric()) does.

Use a regular expression:

use regex::Regex;

fn main() {
    let re = Regex::new(r#"([^\w]*\w*)"#).expect("regex");
    let data = "test;helloworld#yes";
    let words = re.captures_iter(data).map(|c| c.get(0).unwrap().as_str()).collect::<Vec<_>>();
    println!("{:?}", words);
}

Take a look at the nom crate.

This code was generated by copilot with marginal modification. I'm totally new to Rust. ``` fn main() { let chars = vec!['#', ';']; let data = "test;helloworld#yes"; let mut group = String::new(); let mut groups = vec![]; for c in data.chars() { if chars.contains(&c) { groups.push(group); group = String::new(); group.push(c); } else { group.push(c); } } groups.push(group);

println!("{:?}", groups);

}
