Struct ActorStore 

pub struct ActorStore { /* private fields */ }

Lookup structure for storing and retrieving DynActorRefs.

UUID-based references are stored in a HashMap, and path-based named references are stored in a Trie structure.

Notes

The sequence trie supports the use case of grouping many DynActorRef under the same path, similar to a directory structure. Thus, actors can broadcast to all actors under a certain path without requiring explicit identifiers for them.

Ex: Broadcasting a message to actors stored under the system path “tcp://127.0.0.1:8080/pongers/*” Ex: Selecting one of the actors stored under the system path “tcp://127.0.0.1:8080/pongers/?” for delivery

Implementations

impl ActorStore

pub fn new() -> ActorStore

Return a new, empty instance

Trait Implementations

impl ActorLookup for ActorStore

fn insert( &mut self, path: PathResolvable, actor: DynActorRef, ) -> Result<InsertResult, PathParseError>

Inserts or replaces the path in the lookup structure.

fn set_routing_policy( &mut self, path: &[String], policy: StorePolicy, ) -> Result<InsertResult, PathParseError>

Set the routing policy at the provided place in the actor tree to be policy

fn contains(&self, path: &PathResolvable) -> bool

Returns true if the evaluated path is already stored.

fn get_by_uuid(&self, id: &Uuid) -> Option<&DynActorRef>

Lookup the id in the store

fn get_by_named_path<'a, 'b>(&'a self, path: &'b [String]) -> LookupResult<'a>

Lookup the path in the store

fn remove(&mut self, actor: DynActorRef) -> usize

Removes all entries that point to the provided actor, returning how many were removed (most likely O(n), subject to implementation details)

fn remove_by_uuid(&mut self, id: &Uuid) -> bool

Removes the value at the given key, returning true if it existed.

fn remove_by_named_path(&mut self, path: &[String]) -> bool

Removes the value at the given key, returning true if it existed.

fn cleanup(&mut self) -> usize

Performs cleanup on this lookup table, returning how many entries were affected.

fn get_by_actor_path<'a>(&'a self, path: &ActorPath) -> LookupResult<'a>

Lookup the path in the store

impl Clone for ActorStore

fn clone(&self) -> ActorStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for ActorStore

fn default() -> ActorStore

Returns the “default value” for a type.
