//! Serde implementation for PubNub [`Serialize`] trait.
//!
//! This module provides a `serde` serializer for the Pubnub protocol.
//!
//! # Examples
//! ```
//! use pubnub::core::Serialize as _;
//!
//! #[derive(serde::Serialize, serde::Deserialize, Debug, PartialEq)]
//! struct Foo {
//!    bar: String,
//! }
//!
//! let foo = Foo { bar: "baz".to_string() };
//! assert_eq!(foo.serialize().unwrap(), b"{\"bar\":\"baz\"}".to_vec());
//! ```
//!
//! [`Serialize`]: ../trait.Serialize.html
