Enum SubprocessInvokerError 

pub enum SubprocessInvokerError {
    ReceiptEmittedRejected(RouteError),
    Spawn(Error),
    WriteRequest(Error),
    SerializeRequest(Error),
    ReadResponse(Error),
    ParseResponse(Error),
    InvalidResponse(ValidationError),
    NonZeroExit {
        code: Option<i32>,
        stderr: String,
    },
    Timeout,
}

Failure variants surfaced by SubprocessCallbackInvoker::invoke.

Every variant maps deterministically onto a single FailureClass from the shared vocabulary — no new failure classes are introduced by the subprocess transport.

Variants

ReceiptEmittedRejected(RouteError)

Plan rejected before spawn because the event is receipt.emitted (a notification event that must not produce downstream invocations). Maps to FailureClass::InvalidRequest.

Spawn(Error)

Failed to spawn the child (e.g. binary not found, permission denied). Maps to FailureClass::TransportError.

WriteRequest(Error)

Failed to write the request JSON to the child’s stdin. Maps to FailureClass::TransportError.

SerializeRequest(Error)

Failed to serialize the crate::CallbackRequest before writing. Treated as an internal-class failure — the bug is on the Lifeloop side, not the transport.

ReadResponse(Error)

Failed to read the child’s stdout. Maps to FailureClass::TransportError.

ParseResponse(Error)

Child wrote bytes that did not parse as JSON. Maps to FailureClass::InvalidRequest — the response is malformed at the wire layer.

InvalidResponse(ValidationError)

JSON parsed cleanly but the response failed CallbackResponse::validate. Maps to FailureClass::InvalidRequest.

NonZeroExit

Child exited non-zero. Maps to FailureClass::TransportError — the transport returned a failure signal we cannot interpret further.

Fields

code: Option<i32>

stderr: String

Timeout

Round trip exceeded the configured timeout; child was killed. Maps to FailureClass::Timeout.

Trait Implementations

impl Debug for SubprocessInvokerError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SubprocessInvokerError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SubprocessInvokerError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<&SubprocessInvokerError> for FailureClass

fn from(err: &SubprocessInvokerError) -> Self

Converts to this type from the input type.
