pub enum ChildWorkflowSignalError {
    Failed(Box<ChildWorkflowSignalFailureError>),
    Serialization(PayloadConversionError),
}

Error returned when signaling a child workflow fails.

Variants

Failed(Box<ChildWorkflowSignalFailureError>)

The signal delivery failed.

Serialization(PayloadConversionError)

Failed to serialize the signal input payload.

Implementations

impl ChildWorkflowSignalError

pub fn failure(&self) -> Option<&Failure>

Returns the retained top-level child-workflow signal failure proto, if one exists.

pub fn cause(&self) -> Option<&IncomingError>

Returns the normalized cause of the child-workflow signal failure, if any.

pub fn reason(&self) -> Option<&IncomingError>

Returns the underlying failure reason for wrapper-shaped signal failures.

Trait Implementations

impl Debug for ChildWorkflowSignalError

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

Formats the value using the given formatter.

impl Display for ChildWorkflowSignalError

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

Formats the value using the given formatter.

impl Error for ChildWorkflowSignalError

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<ChildWorkflowSignalError> for OutgoingWorkflowError

fn from(value: ChildWorkflowSignalError) -> Self

Converts to this type from the input type.

impl From<PayloadConversionError> for ChildWorkflowSignalError

fn from(source: PayloadConversionError) -> Self

Converts to this type from the input type.
