Trait implemented by VMBus servers.

Required Methods

fn add_child<'life0, 'async_trait>( &'life0 self, request: OfferInput, ) -> Pin<Box<dyn Future<Output = Result<OfferResources>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Offers a new channel.

fn clone_bus(&self) -> Box<dyn ParentBus>

Clones the bus.

TODO: This is needed for now to support transparent subchannel offers. Remove this once subchannels can be pre-created at primary channel offer time.

Provided Methods

fn use_event(&self) -> bool

Returns whether OpenResult::guest_to_host_interrupt needs to be backed by an OS event.

TODO: Remove this and just return the appropriate notify type directly once subchannel creation and enable are separated.
