Lib.rs

一个crate，用于抽象出与paypal接口的网络方面。由nikos创建。

创建支付是通过使用create_payment函数完成的。

let token = paypal::get_token("my_id", "my_secret")?;
let amount = TransactionAmount {
    currency: "USD".to_string(),
    total: "100.00".to_string()
};
let new_payment = payment::new(
    &token.access_token,
    "mysite.com/whooyoupaid",
    "mysite.com/nooyoufailed",
    PaymentMethod::Paypal,
    PaymentIntent::Sale,
    vec![Transaction { amount }],
)?;
