Struct ActorMesh 

pub struct ActorMesh<A: Referable> { /* private fields */ }

An ActorMesh is a collection of ranked A-typed actors.

Bound note: A: Referable because the mesh stores/returns ActorRef<A>, which is only defined for A: Referable.

Implementations

impl<A: Referable> ActorMesh<A>

pub fn id(&self) -> &ActorMeshId

pub async fn stop(&mut self, cx: &impl Actor, reason: String) -> Result<()>

Stop actors on this mesh across all procs.

Methods from Deref<Target = ActorMeshRef<A>>

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

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

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

Cast a message to all the actors in this mesh, merging caller-supplied caller_headers into the per-rank envelope headers before send. Used to propagate caller-known context (e.g. operation-context keys marked with OPERATION_CONTEXT_HEADER) onto the outgoing request so receivers can project it back onto replies.

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

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

Cast a message to one randomly chosen actor in this mesh, merging caller-supplied caller_headers into the outgoing envelope.

pub fn id(&self) -> &ActorMeshId

pub fn controller(&self) -> &Option<ActorRef<ActorMeshController<A>>>

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

Returns the next supervision event occurring on this mesh. Await this simultaneously with the return result of a message (such as awaiting a reply after a cast) to get back a message that indicates the actor that failed, instead of waiting forever for a reply. If there are multiple simultaneous awaits of next_supervision_event, all of them will receive the same event.

pub fn clone_with_supervision_receiver(&self) -> Self

Same as Clone, but includes a shared supervision receiver. This copy will share the same health state and get the same supervision events. Will have a separate cache.

Trait Implementations

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

Manual implementation of Clone because A doesn’t need to implement Clone but we still want to be able to clone the ActorMesh.

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug + Referable> Debug for ActorMesh<A>

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

Formats the value using the given formatter.

impl<A: Referable> Deref for ActorMesh<A>

type Target = ActorMeshRef<A>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

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

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

Formats the value using the given formatter.

impl<A: Referable> Drop for ActorMesh<A>

fn drop(&mut self)

Executes the destructor for this type.
