Module message 

Ergonomic, Rust-facing message types.

These are distinct from the crate-internal wire-format DTOs used to talk to the FCM v1 REST API (see crate::messaging::fcm_v1), so that the public API never exposes Google’s REST field naming or shapes directly.

Structs

AndroidConfig

Android-specific delivery options for a Message.

ApnsConfig

Apple Push Notification Service-specific delivery options for a Message, as a raw APNs payload.

BatchResponse

The response to crate::messaging::MessagingClient::send_each or crate::messaging::MessagingClient::send_each_for_multicast.

Message

A message to send via Firebase Cloud Messaging.

Notification

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

SendError

The error for a single failed message within a batch send.

TopicManagementError

A single failed registration token within a TopicManagementResponse.

TopicManagementResponse

The response to crate::messaging::MessagingClient::subscribe_to_topic or crate::messaging::MessagingClient::unsubscribe_from_topic.

WebpushConfig

Web Push-specific delivery options for a Message.

WebpushNotification

A Web Push display notification, following the Web Notifications API (https://developer.mozilla.org/docs/Web/API/Notification) — the shape FCM forwards verbatim as webpush.notification to the browser’s push event, distinct from Notification’s cross-platform title/body/image.

Enums

SendResult

The outcome of sending a single Message as part of a batch (crate::messaging::MessagingClient::send_each or crate::messaging::MessagingClient::send_each_for_multicast).
