Implementations

impl FirebaseMessaging

pub fn new(middleware: AuthMiddleware) -> Self

Creates a new FirebaseMessaging instance.

This is typically called via FirebaseApp::messaging().

pub async fn send( &self, message: &Message, dry_run: bool, ) -> Result<String, MessagingError>

Sends a message to a specific target (token, topic, or condition).

Arguments

• message - The Message struct defining the payload and target.
• dry_run - If true, the message will be validated but not sent.

pub async fn send_each( &self, messages: &[Message], dry_run: bool, ) -> Result<BatchResponse, MessagingError>

Sends a batch of messages.

This uses the FCM batch endpoint to send up to 500 messages in a single HTTP request.

Arguments

• messages - A slice of Message structs.
• dry_run - If true, the messages will be validated but not sent.

pub async fn send_each_for_multicast( &self, message: &MulticastMessage, dry_run: bool, ) -> Result<BatchResponse, MessagingError>

Sends a multicast message to all specified tokens.

This is a wrapper around send_each that constructs individual messages for each token.

Arguments

• message - The MulticastMessage containing tokens and payload.
• dry_run - If true, the messages will be validated but not sent.

pub async fn subscribe_to_topic( &self, tokens: &[&str], topic: &str, ) -> Result<TopicManagementResponse, MessagingError>

Subscribes a list of tokens to a topic.

Arguments

• tokens - A list of device registration tokens.
• topic - The name of the topic.

pub async fn unsubscribe_from_topic( &self, tokens: &[&str], topic: &str, ) -> Result<TopicManagementResponse, MessagingError>

Unsubscribes a list of tokens from a topic.

Arguments

• tokens - A list of device registration tokens.
• topic - The name of the topic.
