storekit-rs

Safe Rust bindings for Apple's StoreKit framework on macOS.

Status: v0.2.1 closes the remaining audited StoreKit 2 gaps with windowed purchases, formatting/localization helpers, subscription-status streams, purchase intents, external-purchase flows, advanced-commerce APIs, and typed framework errors.

Quick start

use storekit::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let products = Product::products_for(["com.example.pro.monthly"])?;
    for product in products {
        println!("{} — {}", product.display_name, product.display_price);
    }

    println!("payments enabled: {}", AppStore::can_make_payments()?);
    Ok(())
}

Highlights

• Product::products_for(...), Product::purchase(...), Product::purchase_in_window(...), Product::latest_transaction(), and Product::current_entitlements()
• Product formatting/localization helpers expose StoreKit format styles, SubscriptionPeriod convenience constructors, and enum/unit localized_description() helpers
• PurchaseOption covers quantity, app-account tokens, custom payloads, promotional offers, win-back offers, and storefront-change policies
• Transaction exposes all, current_entitlements, updates, unfinished, filtered product streams, latest_for, current_entitlement_for, verification, finishing, refund helpers, and advanced-commerce info
• SubscriptionInfo::status_for(...), status_for_transaction(...), SubscriptionStatus::updates(), and SubscriptionStatus::all() surface renewal state plus status streams
• PurchaseIntent::intents() and ExternalPurchase{,Link,CustomLink} cover the newer StoreKit purchase-intent and regulatory-link families
• AppStore now includes merchandising presentation, age-rating lookups, and advanced-commerce product purchase support
• StoreKitError::typed() recovers typed StoreKit, purchase, refund-request, and invalid-request framework errors
• Storefront::current() and Storefront::updates() wrap the StoreKit storefront APIs
• AppTransaction::shared() and AppTransaction::refresh() expose app-level verification results
• ReceiptValidator reads the local app receipt and decodes JWS payloads without publishing or mutating store state
• StoreContext::current() summarizes bundle, receipt, payment, and device-verification context for headless tooling

Examples

The crate ships with numbered examples for each logical area:

• 01_product_lookup
• 02_transaction_stream
• 03_app_store_context
• 04_storefront_current
• 05_subscription_types
• 06_subscription_info_status
• 07_refund_request
• 08_receipt_validator
• 09_message_support
• 10_app_transaction
• 11_store_context
• 12_renewal_info
• 13_renewal_state
• 14_purchase_option
• 15_verification_result
• 16_purchase_intent
• 17_external_purchase
• 18_advanced_commerce
• 19_typed_errors

Run them all with:

for ex in examples/*.rs; do cargo run --example "$(basename "$ex" .rs)"; done

Notes

• StoreKit.Message is unavailable on macOS, so the message module reports NotSupported there.
• Refund, review, and offer-code presentation helpers still require an NSViewController-backed window; headless callers get NotSupported instead of hanging.
• Window-based purchase and merchandising APIs accept caller-owned NSWindowHandle values when the host app has an AppKit window to lend to StoreKit.
• The crate does not publish or call cargo publish; release tagging is separate from drip-publisher rollout.
