fcm-service – Rust Firebase Cloud Messaging Crate

I developed fcm-service, a Rust library that simplifies integrating Firebase Cloud Messaging (FCM) into Rust applications. This crate enables developers to manage FCM tokens, construct and send push notifications to iOS and Android devices, and handle FCM responses efficiently using a clean, asynchronous API. It is designed for secure, scalable, and fast server-side push notification delivery within Rust-based backends and microservices.
