Struct HidppDevice 

pub struct HidppDevice { /* private fields */ }

A HID++ device with protocol support.

Implementations

impl HidppDevice

pub fn new(channel: HidapiChannel, device_index: u8) -> Self

Creates a new HID++ device wrapper.

Arguments

• channel - HID channel for communication
• device_index - Device index (0xFF for direct, 1-6 for receiver)

pub fn direct(channel: HidapiChannel) -> Self

Creates a device for direct USB/Bluetooth connection.

pub fn channel(&self) -> &HidapiChannel

Returns the underlying HID channel.

pub fn device_index(&self) -> u8

Returns the device index.

pub fn info(&self) -> Option<&DeviceInfo>

Returns device info if initialized.

pub async fn initialize(&mut self) -> Result<&DeviceInfo>

Initializes the device by querying protocol version, name, and features.

This should be called after creating the device to populate device info.

Errors

Returns an error if HID++ communication fails or the device doesn’t respond.

Panics

Panics if called after successful initialization (info already set).

pub fn has_feature(&self, feature_id: u16) -> bool

Checks if a feature is supported by this device.

pub fn get_feature_index(&self, feature_id: u16) -> Option<u8>

Gets the feature index for a given feature ID.
