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.
