Implementations

impl EventHandler

pub(crate) fn new() -> Self

Create a new event handler with internal message and command channels.

pub(crate) fn sender(&self) -> UnboundedSender<Message>

Returns a sender that background tasks can use to push messages.

pub(crate) fn command_sender(&self) -> UnboundedSender<RadioCommand>

Returns a sender the app can use to send commands to the radio task.

pub(crate) const fn take_command_receiver( &mut self, ) -> UnboundedReceiver<RadioCommand>

Takes the command receiver (can only be called once).

Panics

Panics if the command receiver has already been taken.

pub(crate) async fn next(&mut self) -> Message

Wait for the next message from any source (terminal input or background tasks).
