Struct FirebaseApp 

pub struct FirebaseApp { /* private fields */ }

The entry point for the Firebase Admin SDK.

FirebaseApp holds the service account credentials and acts as a factory for creating clients for specific Firebase services (Auth, Messaging, etc.).

It uses a “synchronous constructor, lazy async authentication” pattern. The new method is synchronous and cheap, while the actual OAuth2 authentication happens asynchronously and lazily upon the first API request made by any service client.

Implementations

impl FirebaseApp

pub fn new(service_account_key: ServiceAccountKey) -> Self

Creates a new FirebaseApp instance.

This method is synchronous. The service account key is stored, but no network requests are made until a service (like auth() or messaging()) actually performs an action.

Arguments

• service_account_key - A yup_oauth2::ServiceAccountKey struct containing the credentials.

pub fn auth(&self) -> FirebaseAuth

Returns a client for interacting with Firebase Authentication.

pub fn messaging(&self) -> FirebaseMessaging

Returns a client for interacting with Firebase Cloud Messaging (FCM).

pub fn remote_config(&self) -> FirebaseRemoteConfig

Returns a client for interacting with Firebase Remote Config.

pub fn crashlytics(&self) -> FirebaseCrashlytics

Returns a client for interacting with Firebase Crashlytics.

pub fn firestore(&self) -> FirebaseFirestore

Returns a client for interacting with Cloud Firestore.

pub fn storage(&self) -> FirebaseStorage

Returns a client for interacting with Firebase Storage.
