}
Expand description

Terminal result for one matched request completion.

Variants§

§

Success

Protocol success with the reclaimed caller chain.

Fields

§output: O::Output

Typed response value. Bulk read bytes remain in chain.

§chain: C

Reclaimed caller-owned chain.

§

DeviceError

Well-formed protocol error; operation metadata is returned for retry decisions.

Fields

§status: StatusCode

Raw status, preserving unknown provider values.

§disposition: FailureDisposition

Whether typed operation ownership is retryable, invalid, or uncertain.

§operation: O

Original typed operation.

§chain: C

Reclaimed caller-owned chain.

§

InvalidResponse

Malformed or inaccessible response; reset is required.

Fields

§error: ResponseError<CE>

Validation failure.

§operation: O

Original typed operation.

§chain: C

Reclaimed caller-owned chain.
