Enum ChildWorkflowStartError 

pub enum ChildWorkflowStartError {
    Cancelled(Box<CancelledError>),
    StartFailed {
        workflow_id: String,
        workflow_type: String,
        cause: StartChildWorkflowExecutionFailedCause,
    },
    Serialization(PayloadConversionError),
}

Error returned when starting a child workflow fails.

Variants

Cancelled(Box<CancelledError>)

The child workflow start was cancelled before the normal execution wrapper path existed.

StartFailed

The child workflow failed to start (e.g., workflow ID already exists).

Fields

workflow_id: String

The workflow ID that was requested.

workflow_type: String

The workflow type that was requested.

cause: StartChildWorkflowExecutionFailedCause

The cause of the start failure.

Serialization(PayloadConversionError)

Failed to serialize child workflow input payloads.

Implementations

impl ChildWorkflowStartError

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

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

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

Returns the normalized cause of the retained failure proto, if any.

Trait Implementations

impl Debug for ChildWorkflowStartError

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

Formats the value using the given formatter.

impl Display for ChildWorkflowStartError

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

Formats the value using the given formatter.

impl Error for ChildWorkflowStartError

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<ChildWorkflowStartError> for OutgoingWorkflowError

fn from(value: ChildWorkflowStartError) -> Self

Converts to this type from the input type.

impl From<PayloadConversionError> for ChildWorkflowStartError

fn from(source: PayloadConversionError) -> Self

Converts to this type from the input type.
