Enum DriverError 

pub enum DriverError {
    StreamClosed,
    ResponseDropped,
    Abandoned,
}

Failures in the step-stream driver.

Variants

StreamClosed

The consumer side of the step channel was dropped.

ResponseDropped

One side of a response promise was dropped before delivery.

Abandoned

The consumer took the call’s contents with CallModel::into_parts instead of answering it, so the run ends here by the consumer’s choice. Distinct from ResponseDropped, which means the promise was lost.

Trait Implementations
