Module contains 

Containment check utilities.

This module provides functions for checking whether strings contain specific characters or substrings, including case-insensitive variants and checks for character sets.

Usage

Import the StringContains trait to use methods directly on strings:

use rstring::StringContains;

assert!("zzabyycdxx".contains_any_char(&['z', 'a']));
assert!("abab".contains_only("abc"));
assert!("abc".contains_ignore_case("A"));
