Struct Message 

pub struct Message {
    pub target: Target,
    pub notification: Option<Notification>,
    pub data: HashMap<String, String>,
    pub android: Option<AndroidConfig>,
    pub apns: Option<ApnsConfig>,
    pub webpush: Option<WebpushConfig>,
}

A message to send via Firebase Cloud Messaging.

Exactly one of Self::target must be set to a token, topic, or condition — this is enforced by Target being a single field rather than three optional ones.

Fields

target: Target

Who the message is delivered to.

notification: Option<Notification>

A simple, display notification shown by the client’s OS.

data: HashMap<String, String>

Custom key-value payload delivered to the client app.

android: Option<AndroidConfig>

Android-specific delivery options.

apns: Option<ApnsConfig>

Apple Push Notification Service-specific delivery options, as a raw APNs payload (aps dictionary and custom keys).

webpush: Option<WebpushConfig>

Web Push-specific delivery options.
