Implementations

impl RuntimeError

pub fn runtime_summary(&self) -> Option<&RuntimeSummary>

Returns structured outcomes when execution reached a failing phase.

pub fn execution_cause(&self) -> Option<&RuntimeError>

Returns the underlying execution cause when a phase failed.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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<ConfigurationError> for RuntimeError

fn from(source: ConfigurationError) -> Self

Converts to this type from the input type.
