kebab_case.rs

1//! Converts `String` to [kebab case](https://en.wikipedia.org/wiki/Letter_case#Special_case_styles).
2//! This method is like `find` except that it iterates over elements of
3//! `collection` from right to left.
4//!
5//! Example
6//! ```
7//! use lodash_rust::kebab_case;
8//! 
9//! fn main() {
10//!  let value = String::from("Foo Bar")
11//!  let res = kebab_case::new(value);
12//!  println!("{res}") // "foo-bar"
13//! }
14//! ```
