Enum ActorMeshRef 

pub enum ActorMeshRef<A: Referable> {
    Managed(Box<ManagedActorMeshRef<A>>),
    Data(DataActorMesh<A>),
}

A reference to a stable snapshot of an ActorMesh: the cast and address surface, cheap to clone and to serialize.

Managed is the controller-backed ref, and Data is the detached ref. Both variants use cast-tree delivery and expose the same dense view::Ranked and view::RankedSliceable surface.

Variants

Managed(Box<ManagedActorMeshRef<A>>)

Data(DataActorMesh<A>)

Implementations

impl<A: Referable> ActorMeshRef<A>

pub fn try_new_data( id: ActorMeshId, region: Region, members: Vec<ActorRef<A>>, ) -> Result<Self>

Create a data-only ref named id from a region and its actor refs.

pub fn as_managed(&self) -> Option<&ManagedActorMeshRef<A>>

Return the legacy dense ref when this is the managed variant.

pub fn as_managed_mut(&mut self) -> Option<&mut ManagedActorMeshRef<A>>

Return the legacy dense ref mutably when this is the managed variant.

pub fn id(&self) -> &ActorMeshId

Return the mesh id.

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

where A: RemoteHandles<M>, M: RemoteMessage + Clone,

Cast a message to all the actors in this mesh.

This initiates delivery without waiting for it; use Self::monitor to observe actors that stop or fail.

pub fn cast_with_headers<M>( &self, cx: &impl Actor, caller_headers: &Flattrs, message: M, ) -> Result<()>

where A: RemoteHandles<M>, M: RemoteMessage + Clone,

pub fn cast_with_return_undeliverable<M>( &self, cx: &impl Actor, caller_headers: &Flattrs, message: M, return_undeliverable: bool, ) -> Result<()>

where A: RemoteHandles<M>, M: RemoteMessage + Clone,

Cast message with explicit undeliverable-return behavior.

pub async fn next_supervision_event( &self, cx: &impl Actor, ) -> Result<MeshFailure, Error>

Return the next supervision event observed on this mesh.

pub fn clone_with_supervision_receiver(&self) -> Self

See ManagedActorMeshRef::clone_with_supervision_receiver.

pub fn monitor(&self, cx: &impl Actor) -> MeshMonitor

Create a new, independent monitor over every rank.

Trait Implementations

impl<A: Referable> Clone for ActorMeshRef<A>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Referable> Debug for ActorMeshRef<A>

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

Formats the value using the given formatter.

impl<'de, A: Referable> Deserialize<'de> for ActorMeshRef<A>

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<A: Referable> Display for ActorMeshRef<A>

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

Formats the value using the given formatter.

impl<A: Referable> Eq for ActorMeshRef<A>

impl<A: Referable> Hash for ActorMeshRef<A>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<A: Referable + Named> Named for ActorMeshRef<A>

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

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

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

A globally unique numeric identifier for this type.

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<A: Referable> PartialEq for ActorMeshRef<A>

fn eq(&self, other: &Self) -> 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<A: Referable> Ranked for ActorMeshRef<A>

type Item = ActorRef<A>

The type of item in this view.

fn region(&self) -> &Region

The ranks contained in this view.

fn get(&self, rank: usize) -> Option<&Self::Item>

Return the item at rank

impl<A: Referable> RankedSliceable for ActorMeshRef<A>

fn sliced(&self, region: Region) -> Self

Construct a new Ranked containing the ranks in this view that are part of region. The caller guarantees that region.is_subset(self.region()).

impl<A: Referable> Serialize for ActorMeshRef<A>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
