Part of srad, a general purpose Sparkplug development library in rust.

Overview

srad-app provides a general implementation of a Sparkplug application (see Application) which supports:

• Node and Device state management
• Message sequence reordering
• Detecting situations where an Application may require a node to issue a rebirth message

The generic application should be able to support the majority of use cases required from a Sparkplug application.

For more specific custom implementations srad-app also provides a poll-able [AppEventLoop] and [AppClient] to be used as the base for implementing Sparkplug Applications.

The EventLoop processes Sparkplug messages produced by a specified srad-client implementation. It provides:

• Application topic subscription management
• Application online state management
• Payload validation and transformation to ergonomic types
