Enum strymon_model::TopicSchema

pub enum TopicSchema {
    Stream(TopicType, TopicType),
    Service(TopicType),
}

The kind of protocol used in a topic.

A topic can either be a Stream topic, which provides access to a published Timely Dataflow edge, or it be of the Service, which it describes the interface of an request-response kind of service.

See also the strymon_job crate for more information on topics.

Variants
