Struct ChangeHostFeature 

pub struct ChangeHostFeature { /* private fields */ }

Implements the ChangeHost / 0x1814 feature.

Implementations

impl ChangeHostFeature

pub async fn get_host_info(&self) -> Result<ChangeHostInfo, Hidpp20Error>

Retrieves the host count, current host and host-switching flags.

pub async fn set_current_host(&self, host: u8) -> Result<(), Hidpp20Error>

Selects host as the current host.

This is sent fire-and-forget: a successful switch usually resets the device, so no response is awaited. The device drops off the current host once it acts on the request.

pub async fn get_cookies(&self, host_count: u8) -> Result<Vec<u8>, Hidpp20Error>

Retrieves the persistent per-host cookie bytes.

host_count is the value from ChangeHostInfo::host_count; the device returns one cookie byte per host and does not delimit the list.

pub async fn set_cookie(&self, host: u8, cookie: u8) -> Result<(), Hidpp20Error>

Writes the persistent cookie byte for host.

Cookies are arbitrary software-defined bytes stored in the device’s non-volatile memory; the firmware clears a host’s cookie when a new host connects to that slot.
