Implementations

impl Error

pub fn erase<T: Error + Send + Sync + Debug + 'static>(input: T) -> Self

pub fn downcast_ref<T: Error + Send + Sync + Debug + 'static>( &self, ) -> Option<&T>

Downcasts to the concrete input value.

pub fn downcast_mut<T: Error + Send + Sync + Debug + 'static>( &mut self, ) -> Option<&mut T>

Downcasts to the concrete input value.

pub fn downcast<T: Error + Send + Sync + Debug + 'static>( self, ) -> Result<T, Self>

Downcasts to the concrete input value.

pub fn doesnt_matter() -> Self

Available on crate feature test-util only.

Returns a Error with a fake/test value with the expectation that it won’t be downcast in the test.

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

Formats the value using the given formatter.

impl Display for Error

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<Error> for OrchestratorError<Error>

fn from(err: Error) -> Self
