Struct OneshotAck 

pub struct OneshotAck { /* private fields */ }

Lightweight one-shot acknowledgment channel.

Replaces crossbeam_channel::bounded(1) used for Sync and Clear command round-trips. Works in both std and no_std environments.

The caller creates an Arc<OneshotAck>, sends it in a Command, and blocks on wait(). The Daemon calls signal() after processing.

Implementations

impl OneshotAck

pub fn new() -> Arc<Self>

Allocate a new, unsignalled ack handle.

pub fn signal(&self)

Daemon: signal that the command has been processed.

pub fn wait(&self)

Caller: spin until the signal arrives.

In std mode this is a brief spin (Sync/Clear commands are rare). In no_std / RTOS mode the RTOS scheduler preempts the spinning task.
