Features

This package provides the base interfaces used by the SDK. In particular:

  • CloudEvent is the main interface representing a read only CloudEvent in-memory representation
  • Extension represents a materialized in-memory representation of a CloudEvent extension
  • SpecVersion is an enum of CloudEvents' specification versions supported by this SDK version.
  • CloudEventVisitor/CloudEventVisitable are the interfaces used by the SDK to implement protocol bindings/event formats. A 3rd party implementer can implement these interfaces directly in its CloudEvent in order to customize/implement efficiently the marshalling/unmarshalling process. These interfaces are optional and, if your CloudEvent doesn't implement it, a default implementation is provided by the SDK.

cloudevents-core provides the implementation of these interfaces, and a 3rd party implementer can grab this package to implement specialized CloudEvent in-memory representations.
