rust regex split

To split a string using regular expressions in Rust, you can use the split method provided by the Regex struct from the regex crate. Here's an example:

use regex::Regex;

fn main() {
    let input = "Hello, World! How are you?";
    let pattern = r"[,!?\s]+"; // Split on commas, exclamation marks, question marks, and whitespace

    let re = Regex::new(pattern).unwrap();
    let result: Vec<&str> = re.split(input).collect();

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

In this example, we import the Regex struct from the regex crate. We define the input string input and the regular expression pattern pattern using a raw string literal (r"..."). The pattern [,!?\s]+ matches one or more occurrences of commas, exclamation marks, question marks, and whitespace.

We create a Regex instance re using Regex::new(pattern). Then, we use the split method provided by Regex to split the input string based on the pattern. The result is collected into a Vec<&str>.

Finally, we print the result using println!("{:?}", result).

Please note that you need to add the regex crate to your Cargo.toml file to use the regex crate in your Rust project. You can add it like this:

[dependencies]
regex = "1.5"

This example uses version 1.5 of the regex crate. Make sure to check for the latest version of the crate.

I hope this helps! Let me know if you have any further questions.
