Struct PayOrder 

pub struct PayOrder {
    pub out_trade_no: String,
    pub total_amount: i64,
    pub subject: String,
    pub body: Option<String>,
    pub notify_url: Option<String>,
    pub return_url: Option<String>,
    pub timeout_express: Option<i64>,
    pub passback_params: Option<String>,
    pub extra: Value,

支付订单 — 对齐 PHP Yansongda\Pay\Pay::alipay()->app() 的订单参数

使用 Builder 模式构建订单内容，通过 PayProvider::pay 发起支付。

PHP 对齐

// PHP yansongda/pay
$order = [
    'out_trade_no' => '202401010001',
    'total_amount' => '88.00',
    'subject'      => '鲜视达商品',
];
Pay::alipay()->app($order);

Rust 用法

use sz_rust_core::pay::{PayOrder, MemoryPayProvider, PayProvider};

let order = PayOrder::new()
    .out_trade_no("202401010001")
    .total_amount(8800)
    .subject("鲜视达商品");

let provider = MemoryPayProvider::new();
let result = provider.pay(order).unwrap();
