//! validater value by regex, supported `String`, other types always return false.
//!
//! # Examples
//! ```
//! # use serde::Serialize;
//! # use valitron::{available::{Regex, MessageKind}, Validatable, Validator};
//! #[derive(Serialize, Debug)]
//! struct Input {
//!     title: String,
//! }
//!
//! let input = Input {
//!     title: String::from("ac"),
//! };
//! let err = input
//!     .validate(
//!         Validator::new()
//!             .rule("title", Regex::new(r"...")),
//!     )
//!     .unwrap_err();
//!
//! assert!(matches!(
//!     err.get("title").unwrap()[0].kind(),
//!     MessageKind::Regex
//! ));
//!
//! let input = Input {
//!     title: String::from("abc"),
//! };
//! input
//!     .validate(
//!         Validator::new()
//!             .rule("title", Regex::new(r"...")),
