Struct Envelope 

pub struct Envelope {
    pub meta: Meta,
    pub payload: Value,
}

The single wire type flowing between all pipeline nodes.

Generics stop at the node boundary: every Source, Transform, and Sink works on Envelope regardless of the underlying schema. Strongly-typed payloads are opt-in via transforms that deserialize, map, and re-serialize.

Fields

meta: Meta

payload: Value
