Expand description

Represents a named bus: a bus is a broadcast pub/sub network that distributes Events. Events are not stored, only forwarded to attached clients.

Variants§

§

Publish

Fields

§data: Event
§control_handle: BusControlHandle

Publishes event on the bus.

§

EnsurePublish

Fields

§data: Event

Publishes data on bus and only returns when data has been dispatched. Use this if you need guarantees that the data was broadcast before continuing. Note that this ensures that the data will be published to all listening clients, but it cannot guarantee that all clients will have observed the event before it returns.

§

GetClients

Fields

Get list of named clients.

§

WaitForClients

Fields

§clients: Vec<String>
§timeout: i64

Waits for up to timeout (nsec) for all the clients in clients. Returns true if all clients are present on the bus before timeout expired. If result is false, absent will contain the entries in clients that still weren’t present on the bus when the timout expired. Use timeout <= 0 for indefinite wait.

§

WaitForEvent_

Fields

§data: Event
§timeout: i64

Waits for up to timeout (nsec) for an event that matches data. Event equality is performed by comparing all set fields in data. Returns true if event was received before timeout expired. Use timeout <= 0 for indefinite wait.
