//! # Paddle API Client
//!
//! An async client library for interaction with Paddle API, An async and ergonomic wrapper around Paddle's REST HTTP API.
//!
//! Every interaction is done via the [Paddle] client type.
//!
//! ## Init and Usage Example
//!
//! ```rust,no_run
//! use paddle_rust_sdk::Paddle;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     let client = Paddle::new(std::env::var("PADDLE_API_KEY")?, Paddle::SANDBOX)?;
//!
//!     let mut list = client.customers_list();
//!     let mut paginated = list.per_page(2).send();
//!     let customers = paginated.all().await?;
//!
//!     dbg!(customers);
//!
//!     Ok(())
//! }
//! ```
//!
//! The `examples/` dir has up to date working example code.
//!
//! ## Webhook signature verification
//!
//! Use the [Paddle::unmarshal] method to verify that received events are genuinely sent from Paddle. Additionally, this method returns the deserialized event struct.
//!
