//! This is a small crate to end tweets or sentences with Style.
//!
//! This crate is inspired by [rgbkrk](https://github.com/rgbkrk/covfefe) and
//! the [45th president](https://archive.is/f7UL3) of the United States of America.
//! It basically consists of a _Trait_ - `Cofveve`, which is implemented for all
//! types that implement [`ToString`](https://doc.rust-lang.org/std/string/trait.ToString.html).
//!
//! ## Example
//! ```
//! # use covfefify::Covfefe;
//! println!("{}", "Despite the constant negative press".covfefify());
//! ```
