Struct RootFeature 

pub struct RootFeature { /* private fields */ }

Implements the Root / 0x0000 feature that every HID++2.0 device supports by default.

This implementation is added automatically to any crate::device::Device created using crate::device::Device::new.

Implementations

impl RootFeature

pub async fn get_feature( &self, id: u16, ) -> Result<Option<FeatureInformation>, Hidpp20Error>

Retrieves information about a specific feature ID, including its index in the feature table, its type and its version.

If the feature is not supported by the device, None is returned.

If the device only supports the root feature version 1, the FeatureInformation::version field will be 0 for all features.

pub async fn ping(&self, data: u8) -> Result<u8, Hidpp20Error>

Pings the device with an arbitrary data byte. The device will respond with the same data if communication succeeds.

The underlying function, as described in the protocol specification, will also look up the protocol version supported by the device.
This is not implemented here, as the crate::protocol::determine_version function does so in a more general manner.

Trait Implementations

impl Clone for RootFeature

fn clone(&self) -> RootFeature

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CreatableFeature for RootFeature

const ID: u16 = 0x0000

The protocol ID of the implemented feature.

const STARTING_VERSION: u8 = 0

The version of the feature the implementation starts to support.

fn new(chan: Arc<HidppChannel>, device_index: u8, _: u8) -> Self

Creates a new instance of the feature implementation.
