Struct OncePortRef 

pub struct OncePortRef<M> { /* private fields */ }

A remote reference to a [OncePort]. References are serializable and may be passed to remote actors, which can then use it to send a message to this port.

Implementations

impl<M: RemoteMessage> OncePortRef<M>

pub fn attest_reducible( port_id: PortId, reducer_spec: Option<ReducerSpec>, ) -> Self

The caller attests that the provided PortId can be converted to a reachable, typed once port reference.

pub fn reducer_spec(&self) -> &Option<ReducerSpec>

The typehash of this port’s reducer, if any.

pub fn port_id(&self) -> &PortId

This port’s ID.

pub fn into_port_id(self) -> PortId

Convert this PortRef into its corresponding port id.

pub fn send(self, cx: &impl Actor, message: M) -> Result<(), MailboxSenderError>

Send a message to this port, provided a sending capability, such as [crate::actor::Instance].

pub fn send_with_headers( self, cx: &impl Actor, headers: Flattrs, message: M, ) -> Result<(), MailboxSenderError>

Send a message to this port, provided a sending capability, such as [crate::actor::Instance]. Additional context can be provided in the form of headers.

pub fn get_return_undeliverable(&self) -> bool

Get whether or not messages sent to this port that are undeliverable should be returned to the sender.

pub fn return_undeliverable(&mut self, return_undeliverable: bool)

Set whether or not messages sent to this port that are undeliverable should be returned to the sender.

Trait Implementations

impl<M: RemoteMessage> Bind for OncePortRef<M>

fn bind(&mut self, bindings: &mut Bindings) -> Result<()>

Remove parameters from bindings, and use them to update itself.

impl<M: RemoteMessage> Clone for OncePortRef<M>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug> Debug for OncePortRef<M>

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

Formats the value using the given formatter.

impl<'de, M> Deserialize<'de> for OncePortRef<M>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<M: RemoteMessage> Display for OncePortRef<M>

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

Formats the value using the given formatter.

impl<M: RemoteMessage> From<&OncePortRef<M>> for UnboundPort

fn from(port_ref: &OncePortRef<M>) -> Self

Converts to this type from the input type.

impl Handler<OncePortRef<ActorId>> for EchoActor

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, reply: OncePortRef<ActorId>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle the next M-typed message.

impl<M: RemoteMessage> Named for OncePortRef<M>

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl<M: PartialEq> PartialEq for OncePortRef<M>

fn eq(&self, other: &OncePortRef<M>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<M> Serialize for OncePortRef<M>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<M: RemoteMessage> Unbind for OncePortRef<M>

fn unbind(&self, bindings: &mut Bindings) -> Result<()>

Extract parameters from itself and store them in bindings.

impl Accepts<OncePortRef<ActorId>> for EchoActor

impl RemoteHandles<OncePortRef<ActorId>> for EchoActor
