Struct ReprogControlsFeature 

pub struct ReprogControlsFeature { /* private fields */ }

Reprogrammable Controls feature implementation.

Implementations

impl ReprogControlsFeature

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

Creates a new reprogrammable controls feature accessor.

Arguments

• device_index - Device index (0xFF for direct)
• feature_index - Feature index from root feature discovery

pub fn feature_index(&self) -> u8

Returns the feature index.

pub async fn get_count(&self, channel: &HidapiChannel) -> Result<u8>

Gets the number of controls on the device.

Errors

Returns an error if HID++ communication fails.

pub async fn get_control_info( &self, channel: &HidapiChannel, index: u8, ) -> Result<ControlInfo>

Gets information about a control by index.

Arguments

• channel - HID channel
• index - Control index (0 to count-1)

Errors

Returns an error if HID++ communication fails.

pub async fn get_all_controls( &self, channel: &HidapiChannel, ) -> Result<Vec<ControlInfo>>

Gets information about all controls on the device.

Errors

Returns an error if HID++ communication fails.

pub async fn get_cid_reporting( &self, channel: &HidapiChannel, cid: u16, ) -> Result<CidReporting>

Gets the current reporting configuration for a control.

Arguments

• channel - HID channel
• cid - Control ID

Errors

Returns an error if HID++ communication fails.

pub async fn set_cid_reporting( &self, channel: &HidapiChannel, reporting: &CidReporting, ) -> Result<()>

Sets the reporting configuration for a control.

Arguments

• channel - HID channel
• reporting - Reporting configuration

Errors

Returns an error if HID++ communication fails.

pub fn parse_button_event( data: &[u8], feature_index: u8, ) -> Option<Vec<ButtonEvent>>

Parses button events from a HID++ notification.

When buttons are diverted, the device sends HID++ notifications containing button state changes. This function parses such notifications.

Arguments

• data - Raw HID++ report data
• feature_index - Expected feature index

Returns

A vector of button events, or None if this is not a button event notification.

pub fn parse_button_event_with_state( data: &[u8], feature_index: u8, previous_pressed: &HashSet<u16>, ) -> Option<(Vec<ButtonEvent>, HashSet<u16>)>

Parses button events from a HID++ notification, tracking state changes.

This version compares against the previous state to generate both press and release events.

Arguments

• data - Raw HID++ report data
• feature_index - Expected feature index
• previous_pressed - Set of CIDs that were pressed in the previous state

Returns

A tuple of (events, new_pressed_set), or None if not a button event.
