The regex crate doesn't provide split_inclusive, which is found in the standard library for string, etc. There's an unstable feature that allows a regex to be used as the search pattern for a split, yadda yadda, etc., but who wants to use unstable these days?
Anyway, this library adds split_inclusive and split_inclusive_left, with the difference being that split_inclusive_left places the delimiter at the beginning of the substring, where split_inclusive places it at the end.
First, add the package.
shell
$ cargo add regex-split
Then import regex_split::RegexSplit wherever you'd like to use the extra methods. Consuming the new methods is straightforward.
```rust use regex_split::RegexSplit;
// splitinclusive let re = Regex::new("\r?\n").unwrap(); let text = "This is just\na set of lines\r\nwith different newlines."; let v: Vec<&str> = re.splitinclusive(text).collect();
assert_eq!(v, [ "This is just\n", "a set of lines\r\n", "with different newlines.", ]);
// splitinclusiveleft let re = Regex::new("(?m)^-").unwrap(); let text = "List of fruits:\n-apple\n-pear\n-banana"; let v: Vec<&str> = re.splitinclusiveleft(text).collect();
assert_eq!(v, [ "List of fruits:\n", "-apple\n", "-pear\n", "-banana", ]); ```
That's pretty much it.
