Enum RunStream 

pub enum RunStream {
    Execute(Pin<Box<dyn Stream<Item = Result<ResponseItem, Error>> + Send>>),
    ExecuteTransform(Pin<Box<dyn Stream<Item = Result<Value, Error>> + Send>>),
}

What run yields, mirroring the two SDK root dispatch entry points. The arm is chosen by whether the parsed request carries an output transform (RequestBase::transform):

• RunStream::Execute: no transform — the typed root ResponseItem stream (identical to what run used to return).
• RunStream::ExecuteTransform: a transform is set — each item is the transformed JSON output (serde_json::Value).

Variants

Execute(Pin<Box<dyn Stream<Item = Result<ResponseItem, Error>> + Send>>)

ExecuteTransform(Pin<Box<dyn Stream<Item = Result<Value, Error>> + Send>>)
