//! 对alipay api的简单封装
//!
//! # Usage:
//! ```toml
//! [dependencies]
//! alipay-rs = {git = "https://github.com/chenhuaiyuan/alipay-rs"}
//! 已在原先的alipay-rs库中删除AlipayParam宏，需要添加struct-map库来实现AlipayParam宏，如果未使用到AlipayParam宏可以不添加
//! struct-map = {git = "https://github.com/chenhuaiyuan/struct-map"}
//!
//! or
//!
//! alipay-rs = "0.2"
//! struct-map = "0.1"
//! ```
//!
//! # Example:
//! ```rust
//! // 默认的公共参数只包含了最基础的，如果需要增加公共参数，可用通过set_public_params函数实现  
//! // 默认的公共参数包含：app_id，charset，sign_type，format，version，method，timestamp，sign  
//! // 通过set_public_params设置公共参数，如果参数值为None会自动过滤，重复的参数后面的值会覆盖前面的值  
//! // 下面是单笔转账的几种示例  
//! use serde::Serialize;
//! use chrono::{Local};
//! use alipay_rs::AlipayParam;
//!
