string-replace-all

The string-replace-all crate provides a utility to return a new String with all occurrences of a pattern replaced by a specified replacement.

• The pattern can be either a string slice or a Regex.
• The replacement is always a string slice.
• The original input string remains unchanged.

This functionality is inspired by JavaScript’s replaceAll(), with the key difference that only string slices are supported as replacements at this time.

Installation

cargo add string-replace-all

Usage

use string_replace_all::string_replace_all;

let text = "I think Ruth's dog is cuter than your dog!";

let result = string_replace_all(text, "dog", "monkey");
assert_eq!(result, "I think Ruth's monkey is cuter than your monkey!");

use regex::Regex;
use string_replace_all::string_replace_all;

let text = "I think Ruth's dog is cuter than your dog!";
let regex = Regex::new("(?i)Dog").unwrap(); // Case-insensitive regex

let result = string_replace_all(text, &regex, "ferret");
assert_eq!(result, "I think Ruth's ferret is cuter than your ferret!");
