Struct SetStepModeFuture

pub struct SetStepModeFuture<Driver, Timer, const TIMER_HZ: u32>
where
    Driver: SetStepMode,
{ /* private fields */ }

The “future” returned by Stepper::set_step_mode

Please note that this type provides a custom API and does not implement core::future::Future. This might change, when using futures for embedded development becomes more practical.

Implementations

impl<Driver, Timer, const TIMER_HZ: u32> SetStepModeFuture<Driver, Timer, TIMER_HZ>

where Driver: SetStepMode, Timer: Timer<TIMER_HZ>,

pub fn new( step_mode: <Driver as SetStepMode>::StepMode, driver: Driver, timer: Timer, ) -> SetStepModeFuture<Driver, Timer, TIMER_HZ>

Create new instance of SetStepModeFuture

This constructor is public to provide maximum flexibility for non-standard use cases. Most users can ignore this and just use Stepper::set_step_mode instead.

pub fn poll( &mut self, ) -> Poll<Result<(), SignalError<Infallible, <Driver as SetStepMode>::Error, <Timer as Timer<TIMER_HZ>>::Error>>>

Poll the future

The future must be polled for the operation to make progress. The operation won’t start, until this method has been called once. Returns Poll::Pending, if the operation is not finished yet, or Poll::Ready, once it is.

If this method returns Poll::Pending, the user can opt to keep calling it at a high frequency (see Self::wait) until the operation completes, or set up an interrupt that fires once the timer finishes counting down, and call this method again once it does.

pub fn wait( &mut self, ) -> Result<(), SignalError<Infallible, <Driver as SetStepMode>::Error, <Timer as Timer<TIMER_HZ>>::Error>>

Wait until the operation completes

This method will call Self::poll in a busy loop until the operation has finished.

pub fn release(self) -> (Driver, Timer)

Drop the future and release the resources that were moved into it
