Firebase Admin SDK for Rust

The Firebase Admin Rust SDK enables access to Firebase services from privileged environments. Designed to be scalable and reliable with zero-overhead for performance in mind.

Currently supports

• GCP service accounts
• User and custom authentication management
• Firebase emulator integration and management
• Firebase OIDC token and session cookie verification using asynchronous public certificate cache

Example for interacting with Firebase on GCP

use rs_firebase_admin_sdk::{
auth::{FirebaseAuthService,UserIdentifiers},
client::ApiHttpClient,App,};// Create live (not emulated) context for Firebase applet live_app = App::live().await.unwrap();// Create Firebase authentication admin clientlet auth_admin = live_app.auth();let user = auth_admin.get_user(// Build a filter for finding the userUserIdentifiers::builder().with_email("me@email.com".into()).build()).await.expect("Error while fetching user").expect("User does not exist");println!("User id: {}", user.uid);

Example with an explicit project ID

Use App::live_with_project_id when your Firebase project differs from the GCP project in GOOGLE_CLOUD_PROJECT — for example when identity management runs in a separate project from Cloud Storage and other infrastructure services.

use rs_firebase_admin_sdk::{
auth::{FirebaseAuthService,UserIdentifiers},
client::ApiHttpClient,App,};// Supply the Firebase project ID directly instead of reading GOOGLE_CLOUD_PROJECTlet live_app = App::live_with_project_id("my-firebase-project-id").unwrap();
