Function string_find_value 

pub fn string_find_value<T: Default + FromStr>(
    input: &str,
    patterns: &[&str],
) -> RUMResult<T>

Given a string input and a set of RegEx patterns, find the target value and return it as the given target type T.

use rumtk_core::search::rumtk_search::string_find_value;

let haystack = "Range (min \\xe2\\x80\\xa6 max):     0.6 ms \\xe2\\x80\\xa6   2.9 ms    1273 runs";
let patterns = ["\\d+ runs", "\\d+"];
let expected = 1273;
let result = string_find_value::<usize>(haystack, &patterns);

assert_eq!(result, Ok(expected), "Did not find the needle in the haystack or returned the wrong type!");

Use " " in join_pattern if you wish to have spaces in between matches.
