Struct kernel::services::keyboard::mux::KeyboardMuxClient

pub struct KeyboardMuxClient {
    handle: KernelHandle<KeyboardMuxService>,
    reply: Reusable<Envelope<Result<Response, Infallible>>>,
}

A client for the KeyboardMuxService.

This type is used by keyboard drivers to broadcast events from their hardware keyboard to the KeyboardMuxService. It is obtained using KeyboardMuxClient::from_registry.

Fields

handle: KernelHandle<KeyboardMuxService>

reply: Reusable<Envelope<Result<Response, Infallible>>>

Implementations

impl KeyboardMuxClient

pub async fn from_registry( kernel: &'static Kernel, ) -> Result<Self, ConnectError<KeyboardMuxService>>

Obtain a KeyboardMuxClient

If the KeyboardMuxService hasn’t been registered yet, we will retry until it has been registered.

pub async fn from_registry_no_retry( kernel: &'static Kernel, ) -> Result<Self, ConnectError<KeyboardMuxService>>

Obtain an KeyboardMuxClient

Does NOT attempt to get an KeyboardMuxService handle more than once.

Prefer KeyboardMuxClient::from_registry unless you will not be spawning one around the same time as obtaining a client.

pub async fn publish_key( &mut self, event: impl Into<KeyEvent>, ) -> Result<(), OneshotRequestError>
