Implementations

impl ChildWorkflowExecutionError

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

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

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

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

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

Returns the underlying failure reason for wrapper-shaped child-workflow failures.

pub fn as_timeout(&self) -> Option<&TimeoutError>

If this ChildWorkflowExecutionError was caused by a timeout, returns the associated TimeoutError.

pub fn as_cancelled(&self) -> Option<&CancelledError>

If this ChildWorkflowExecutionError was caused by a cancellation, returns the associated CancelledError.

Trait Implementations

impl Display for ChildWorkflowExecutionError

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

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
