//! # Serde Str
//!
//! [Documentation](https://docs.rs/) |
//! [Github](https://github.com/tailhook/serde-str) |
//! [crates.io](https://crates.io/crates/) |
//! [lib.rs](https://lib.rs/)
//!
//! A (de)serializer for anything that has implemented `FromStr` / `Display`
//! but does not have `Serialize`/`Deserialize`.
//!
//! # Example
//!
//! ```rust
//! # #[macro_use] extern crate serde_derive;
//! use std::net::IpAddr;
//!
//! /// A demonstration structure that holds a lonesome IP address.
//! #[derive(Serialize, Deserialize)]
//! # #[derive(PartialEq, Debug)]
//! struct WithIp {
//! 	#[serde(with = "serde_strz")]
//! 	ip: IpAddr,
//! }
//!
//! use serde_json::{
//! 	from_str,
//! 	to_string,
//! };
//! # fn main() -> serde_json::Result<()> {
//! let with_ip: WithIp = from_str(r#"{"ip": "127.0.0.1"}"#)?;
//! assert_eq!(WithIp { ip: [127, 0, 0, 1].into() }, with_ip);
//! assert_eq!(to_string(&with_ip)?, r#"{"ip":"127.0.0.1"}"#);
//!
//! let with_ip: WithIp = from_str(r#"{"ip": "::"}"#)?;
//! assert_eq!(WithIp { ip: [0u16; 8].into() }, with_ip);
//! assert_eq!(to_string(&with_ip)?, r#"{"ip":"::"}"#);
//! # Ok(())
//! # }
//! ```
