Expand description

Trait implemented by VMBus devices.

Required Methods§

Source

fn offer(&self) -> OfferParams

The offer parameters.

Source

fn install(&mut self, resources: DeviceResources)

Installs resources used by the device.

Source

fn open<'life0, 'life1, 'async_trait>( &'life0 mut self, channel_idx: u16, open_request: &'life1 OpenRequest, ) -> Pin<Box<dyn Future<Output = Result<(), ChannelOpenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Opens the channel number channel_idx.

Source

fn close<'life0, 'async_trait>( &'life0 mut self, channel_idx: u16, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Closes the channel number channel_idx.

Source

fn retarget_vp<'life0, 'async_trait>( &'life0 mut self, channel_idx: u16, target_vp: u32, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Notifies the device that interrupts for channel will now target target_vp.

Source

fn start(&mut self)

Start processing of all channels.

Source

fn stop<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Stop processing of all channels.

Source

fn supports_save_restore(&mut self) -> Option<&mut dyn SaveRestoreVmbusDevice>

Returns a trait used to save/restore the channel.

Returns None if save/restore is not supported, in which case the channel will be revoked and reoffered on restore.

Provided Methods§

Source

fn max_subchannels(&self) -> u16

The maximum number of subchannels supported by this device.
