Implementations

impl FcmService

pub fn new(credential_file: impl Into<String>) -> Self

impl FcmService

Service for sending Firebase Cloud Messaging (FCM) notifications using the v1 API.

This service uses a Google Cloud service account credential file to authenticate and send notifications to FCM.

Examples

use fcm_service::{FcmService, FcmMessage, FcmNotification, Target};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let service = FcmService::new("path/to/service-account.json");

    let mut message = FcmMessage::new();
    let mut notification = FcmNotification::new();
    notification.set_title("Hello".to_string());
    notification.set_body("World".to_string());
    notification.set_image(None);
    message.set_notification(Some(notification));
    message.set_target(Target::Token("device-token".to_string()));

    service.send_notification(message).await?;
    Ok(())
}

pub async fn send_notification( &self, message: FcmMessage, ) -> Result<(), Box<dyn Error>>

Sends an FCM notification asynchronously.

Errors

Returns an error if:

• The credential file cannot be read or parsed
• Authentication with GCP fails
• The HTTP request to FCM fails
• The FCM API returns an unsuccessful status
