Struct DeviceApi

pub struct DeviceApi<D, C>(/* private fields */);

The device API.

Implementations

impl<D, C> DeviceApi<D, C>

pub fn new(ctx: C) -> Self

Creates a new DeviceApi from ctx.

impl<D, C> DeviceApi<D, C>

where D: Device + DeviceStateSpec + DeviceReceiveFrameSpec, C: ContextPair, C::CoreContext: DeviceApiCoreContext<D, C::BindingsContext>, C::BindingsContext: DeviceApiBindingsContext,

pub fn add_device( &mut self, bindings_id: <C::BindingsContext as DeviceLayerStateTypes>::DeviceIdentifier, properties: D::CreationProperties, metric: RawMetric, external_state: D::External<C::BindingsContext>, ) -> <C::CoreContext as DeviceIdContext<D>>::DeviceId

where C::CoreContext: DeviceApiIpLayerCoreContext<D, C::BindingsContext>,

Adds a new device to the stack and returns its identifier.

Panics

Panics if more than 1 loopback device is added to the stack.

pub fn remove_device( &mut self, device: BaseDeviceId<D, C::BindingsContext>, ) -> RemoveResourceResultWithContext<D::External<C::BindingsContext>, C::BindingsContext>

where BaseDeviceId<D, C::BindingsContext>: Into<DeviceId<C::BindingsContext>>, C::CoreContext: IpDeviceConfigurationContext<Ipv4, C::BindingsContext> + Ipv6DeviceConfigurationContext<C::BindingsContext> + DeviceIdContext<AnyDevice, DeviceId = DeviceId<C::BindingsContext>>, C::BindingsContext: IpDeviceBindingsContext<Ipv4, <C::CoreContext as DeviceIdContext<AnyDevice>>::DeviceId> + IpDeviceBindingsContext<Ipv6, <C::CoreContext as DeviceIdContext<AnyDevice>>::DeviceId>,

Removes device from the stack.

If the return value is RemoveDeviceResult::Removed the device is immediately removed from the stack, otherwise RemoveDeviceResult::Deferred indicates that the device was marked for destruction but there are still references to it. It carries a ReferenceReceiver from the bindings context that can be awaited on until removal is complete.

Panics

Panics if the device is not currently in the stack.

pub fn receive_frame<B: BufferMut + Debug>( &mut self, meta: D::FrameMetadata<BaseDeviceId<D, C::BindingsContext>>, frame: B, )

Receive a device layer frame from the network.

pub fn apply_configuration( &mut self, pending: PendingDeviceConfigurationUpdate<'_, BaseDeviceId<D, C::BindingsContext>>, ) -> DeviceConfigurationUpdate

Applies the configuration and returns a DeviceConfigurationUpdate with the previous values for all configurations for all Some fields.

Note that even if the previous value matched the requested value, it is still populated in the returned DeviceConfigurationUpdate.

pub fn new_configuration_update<'a>( &mut self, device: &'a BaseDeviceId<D, C::BindingsContext>, config: DeviceConfigurationUpdate, ) -> Result<PendingDeviceConfigurationUpdate<'a, BaseDeviceId<D, C::BindingsContext>>, DeviceConfigurationUpdateError>

Creates a new device configuration update for the given device.

This method only validates that config is valid for device. [DeviceApi::apply] must be called to apply the configuration.

pub fn get_configuration( &mut self, device: &BaseDeviceId<D, C::BindingsContext>, ) -> DeviceConfiguration

Returns a snapshot of the given device’s configuration.

pub fn inspect<N: Inspector>( &mut self, device: &BaseDeviceId<D, C::BindingsContext>, inspector: &mut N, )

Exports state for device into inspector.
