//! Value must be a valid email address, supported `String`, and other types always return false.

//! # Examples
//! ```
//! # use serde::Serialize;
//! # use valitron::{available::{Email, MessageKind}, Validatable, Validator};
//! #[derive(Serialize, Debug)]
//! struct Input {
//!     email: String,
//!     password: String,
//! }
//!
//! let input = Input {
//!     email: String::from("user"),
//!     password: String::default(),
//! };
//! let err = input
//!     .validate(
//!         Validator::new()
//!             .rule("email", Email)
//!     )
//!     .unwrap_err();
//!
//! assert!(matches!(
//!     err.get("email").unwrap()[0].kind(),
//!     MessageKind::Email
//! ));
//!
//! let input = Input {
//!     email: String::from("user@example.com"),
//!     password: String::from("bar"),
