pub struct DeviceSynchronousProxy { /* private fields */ }

Implementations

impl DeviceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DeviceEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn provision_network( &self, params: &ProvisioningParams, ___deadline: MonotonicInstant, ) -> Result<(), Error>

Provision the interface for the network described by identity and credential. This is similar to JoinNetwork, except that (assuming the identity and credential are valid) it will (assuming all preconditions are met) always succeed, even if there are no peers nearby.

The following fields of ProvisioningParams MUST be specified:

• identity.raw_name
• identity.xpanid
• identity.panid
• identity.channel_index
• credential

If any of the required fields are unspecified, the channel will be closed with the epitaph ZX_ERR_INVALID_ARGUMENT.

Additionally, if the identity.net_type field is present and does not match a network type supported by this device, the channel will also be closed with the epitaph ZX_ERR_NOT_SUPPORTED.

This method returns once the device has been reconfigured successfully. The resulting change in state can be monitored via WatchDeviceState(). Any error that prevents the operation from completing successfully will result in the protocol being closed.

pub fn leave_network(&self, ___deadline: MonotonicInstant) -> Result<(), Error>

Bring down the network interface and forget all non-volatile details about the current network.

Upon completion, all non-volatile and transient state about the current network is cleared and the interface will be offline.

Specifically, calling this method will cause the following observable effects:

• DeviceState.connectivity_state will transition to State::OFFLINE, assuming it wasn’t in that state already.
• DeviceExtra::WatchIdentity will emit an empty Identity, assuming it wasn’t already empty.

If the interface was not previously provisioned, calling this method does nothing.

pub fn set_active( &self, active: bool, ___deadline: MonotonicInstant, ) -> Result<(), Error>

Activate (“bring-up”) or deactivate (“shut-down”) the network interface.

Note that simply setting this to true does not mean that the network interface will necessarily become online and usable, see the connectivity_state field of the DeviceState table for more information.

This method returns once the operation has completed successfully. The resulting change in state can be monitored via WatchDeviceState(). Any error that prevents the operation from completing successfully will result in the protocol being closed.

pub fn get_supported_network_types( &self, ___deadline: MonotonicInstant, ) -> Result<Vec<String>, Error>

Returns the types of networks supported by this interface.

LoWPAN devices typically only support a single network type, but some devices may support more than one. Up to MAX_NETWORK_TYPES network types may be returned.

pub fn watch_device_state( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceState, Error>

Observes changes to the DeviceState.

First call always returns a snapshot of the current state. Subsequent calls will block until the state has changed and returns the delta against the device’s internal state.

Changes are not queued. The returned value always represents the latest and most accurate state values, even if several changes had happened in-between calls.
