Enum ractor::errors::RactorErr

pub enum RactorErr<T> {
    Spawn(SpawnErr),
    Messaging(MessagingErr<T>),
    Actor(ActorErr),
    Timeout,
}

Error types which can result from Ractor processes

Variants

Spawn(SpawnErr)

An error occurred spawning

Messaging(MessagingErr<T>)

An error occurred in messaging (sending/receiving)

Actor(ActorErr)

An actor encountered an error while processing (canceled or panicked)

Timeout

A timeout occurred

Implementations

impl<T> RactorErr<T>

pub fn has_message(&self) -> bool

Identify if the error has a message payload contained. If true, You can utilize try_get_message to consume the error and extract the message payload quickly.

Returns true if the error contains a message payload of type T, false otherwise.

pub fn try_get_message(self) -> Option<T>

Try and extract the message payload from the contained error. This consumes the RactorErr instance in order to not have require cloning the message payload. Should be used in conjunction with has_message to not consume the error if not wanted

Returns [Some(T)] if there is a message payload, None otherwise.

pub fn map<F, U>(self, mapper: F) -> RactorErr<U>

where F: FnOnce(T) -> U,

Map any message embedded within the error type. This is primarily useful for normalizing an error value if the message is not needed.

Trait Implementations

impl<T> Debug for RactorErr<T>

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

Formats the value using the given formatter.

impl<T> Display for RactorErr<T>

impl<T> Error for RactorErr<T>

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
