let subscription = Subscription::broadcast_events(&agent, "v1", "rooms/123/events");

pub fn multicast_requests<'a>(
    version: Option<&'a str>
) -> RequestSubscription<'a>

    version: Option<&'a str>
) -> RequestSubscription<'a> where
    A: Addressable, 

Builds a RequestSubscription for multicast requests from a specific agent.

This is the same as multicast_requests but subscribes only from requests from a specfic agent.

Arguments

• from – anything Adressable to receive requests from. For example service AgentId.
• version – API version string of the from agent. Example: v1.

Example

let agent = AgentId::new("instance01", AccountId::new("service_name", "svc.example.org"));
let subscription = Subscription::multicast_requests_from(&agent, "v1");

pub fn unicast_requests<'a>() -> RequestSubscription<'a>

Builds a RequestSubscription for unicast requests from any agent.

let subscription = Subscription::unicast_requests();

pub fn unicast_requests_from<A>(from: &A) -> RequestSubscription where
    A: Authenticable, 

Builds a RequestSubscription for unicast requests from a specific agent.

let subscription = Subscription::unicast_requests(&agent);

pub fn unicast_responses<'a>() -> ResponseSubscription<'a>

Builds a ResponseSubscription for unicast requests from any agent.

Use it to subscribe to responses from all services.

let subscription = Subscription::unicast_responses();

pub fn unicast_responses_from<A>(from: &A) -> ResponseSubscription where
    A: Authenticable, 

Builds a ResponseSubscription for unicast requests from a specific agent.

This is the same as unicast_responses but subscribes only from requests from a specfic agent.

Example

let agent = AgentId::new("instance01", AccountId::new("service_name", "svc.example.org"));
let subscription = Subscription::unicast_responses_from(&agent);
