Struct EventQueues 

pub struct EventQueues<E, const DEFERRED: usize, const PROCESSED: usize> { /* private fields */ }

Separate bounded queues for deferred events and events requested by actions.

Implementations

impl<E, const DEFERRED: usize, const PROCESSED: usize> EventQueues<E, DEFERRED, PROCESSED>

pub const fn new() -> Self

Creates empty queues.

pub fn defer(&mut self, event: E) -> Result<(), QueueFull>

Defers an event until a dispatch changes state.

pub fn process(&mut self, event: E) -> Result<(), QueueFull>

Schedules an event for immediate processing after the current action.

pub const fn deferred_len(&self) -> usize

Returns the number of deferred events.

pub const fn processed_len(&self) -> usize

Returns the number of immediately processed events.

pub fn dispatch<M, F>( &mut self, machine: &mut M, event: E, dispatch: F, ) -> DispatchSummary

where F: FnMut(&mut M, &mut Self, E) -> DispatchStatus,

Dispatches an external event, drains action-requested events, and gives each previously deferred event one retry after a state change.

Trait Implementations

impl<E, const DEFERRED: usize, const PROCESSED: usize> Default for EventQueues<E, DEFERRED, PROCESSED>

fn default() -> Self

Returns the “default value” for a type.
