//! Unofficial Rust SDK for the [Pakasir](https://pakasir.com) payment gateway.
//!
//! The crate covers the REST surface of the API plus a few helpers most
//! integrations end up writing anyway:
//!
//! - [`Client`] – async HTTP client with retries, jittered backoff, and
//! `Retry-After` handling.
//! - [`TransactionService`] – create / cancel / detail.
//! - [`SimulationService`] – sandbox payment simulation.
//! - [`WebhookParser`] – parse and validate webhook payloads.
//! - [`build_payment_url`] – build the hosted checkout redirect URL.
//! - [`QrGenerator`] – render QRIS strings (or anything else) to PNG bytes.
//!
//! Error messages are localized through [`Language`] (English by default,
//! Indonesian when the client is configured for it).
//!
//! # Quick start
//!
//! ```no_run
//! use pakasir_sdk::{Client, PaymentMethod, TransactionService};
//! use pakasir_sdk::transaction::CreateRequest;
//!
//! # async fn run() -> Result<(), pakasir_sdk::Error> {
//! let client = Client::builder("your-project-slug", "your-api-key").build();
//! let transactions = TransactionService::new(client);
//!
//! let response = transactions
//! .create(
//! PaymentMethod::Qris,
//! &CreateRequest {
//! order_id: "INV123456".into(),
//! amount: 99_000,
//! },
//! )
//! .await?;
//!
//! println!("payment number: {}", response.payment.payment_number);
//! println!("total payment: {}", response.payment.total_payment);
//! # Ok(())
//! # }
//! ```
//!
//! # Modules
//!
//! | Module | What it does |
//! |-----------------|---------------------------------------------------------------|
//! | [`client`] | HTTP transport, retry policy, builder. |
//! | [`constants`] | SDK metadata, API paths, payment / status enums. |
//! | [`error`] | The crate-wide [`Error`] enum and [`Result`] alias. |
//! | [`i18n`] | Language selector and message catalog. |
//! | [`payment_url`] | Hosted checkout redirect URL builder. |
//! | [`qr`] | QR PNG generation. |
//! | [`simulation`] | Sandbox payment simulation. |
//! | [`timefmt`] | Small RFC 3339 parsing helper. |
//! | [`transaction`] | Transaction service. |
//! | [`webhook`] | Webhook parser and event validation. |
//!
//! The gRPC server layer from the original implementation is not part of
//! this crate.
