This library is no longer maintained.

Google has deprecated and removed GCM APIs to move to FCM (Firebase Cloud Messaging). As such, this library was removed from crates.io on 30th August, 2020. Please use the alternative fcm library instead.

gcm

Usage

Add this to Cargo.toml:

[dependencies]
gcm = "0.2.0"

then add this to your crate root:

extern crate gcm;

Examples:

Here is an example to send out a GCM Message with some custom data:

use gcm::Message;
use std::collections::HashMap;

let mut map = HashMap::new();
map.insert("message", "Howdy!");

let result = Message::new("<registration id>")
    .data(map)
    .send("<GCM API Key>");

To send a message using GCM Notifications, we first build the notification:

use gcm::{Message, NotificationBuilder};

let notification = NotificationBuilder::new("Hey!")
    .body("Do you want to catch up later?")
    .finalize();

And then set it in the message, before sending it:

let result = Message::new("<registration id>")
    .notification(notification)
    .send("<GCM API Key>");

You can now handle the result accordingly:

match result {
  Ok(response) => println!("message_id: {:?}", response.message_id),
  Err(error) => println!("Error: {:?}", error),
}
