Struct kernel::services::serial_mux::SerialMuxClient

pub struct SerialMuxClient {
    prod: KernelHandle<SerialMuxService>,
    reply: Reusable<Envelope<Result<Response, SerialMuxError>>>,
}

A SerialMuxClient is the client interface of the SerialMuxService.

This client allows opening virtual serial ports, returning a PortHandle representing the opened port.

Fields

prod: KernelHandle<SerialMuxService>

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

Implementations

impl SerialMuxClient

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

Obtain a SerialMuxClient

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

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

Obtain a SerialMuxClient

Does NOT attempt to get a SerialMuxServer handle more than once.

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

pub async fn open_port( &mut self, port_id: u16, capacity: usize, ) -> Option<PortHandle>
