Handler for HID-related control requests.

Provided Methods

fn get_report(&self, id: ReportId, buf: &mut [u8]) -> Option<usize>

Reads the value of report id into buf returning the size.

Returns None if id is invalid or no data is available.

fn set_report(&self, id: ReportId, data: &[u8]) -> OutResponse

Sets the value of report id to data.

fn get_idle_ms(&self, id: Option<ReportId>) -> Option<u32>

Get the idle rate for id.

If id is None, get the idle rate for all reports. Returning None will reject the control request. Any duration at or above 1.024 seconds or below 4ms will be returned as an indefinite idle rate.

fn set_idle_ms(&self, id: Option<ReportId>, duration_ms: u32)

Set the idle rate for id to dur.

If id is None, set the idle rate of all input reports to dur. If an indefinite duration is requested, dur will be set to u32::MAX.
