Enum Sender 

#[non_exhaustive]
pub enum Sender {
    Local(UntypedActorRef),
    Remote {
        path: ActorPath,
        handle: Arc<dyn RemoteRef>,
    },
    None,
}

Typed identity of a message’s sender.

Three variants:

• Sender::Local — the sender is an actor in this ActorSystem.
• Sender::Remote — the sender lives in another ActorSystem, reached via remoting. Carries a path + a remote handle so replies can be serialized back without a downcast.
• Sender::None — no sender attached (the analog of IActorRef.NoSender).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Sender

pub fn path(&self) -> Option<&ActorPath>

Path of the sender, if any.

pub fn is_remote(&self) -> bool

true iff the sender lives in another actor system.

pub fn is_none(&self) -> bool

true iff the sender slot is empty.

pub fn local(&self) -> Option<&UntypedActorRef>

Borrow the local untyped ref, if this is a local sender.

Trait Implementations

impl Clone for Sender

fn clone(&self) -> Sender

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Sender

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

Formats the value using the given formatter.

impl Default for Sender

fn default() -> Sender

Returns the “default value” for a type.

impl<M: Send + 'static> From<&ActorRef<M>> for Sender

fn from(r: &ActorRef<M>) -> Self

Converts to this type from the input type.

impl From<UntypedActorRef> for Sender

fn from(r: UntypedActorRef) -> Self
