Implementations

impl ButtonFsm

pub fn new(timings: ButtonTimings) -> Self

pub fn on_edge(&mut self, edge: ButtonEdge, now_ms: u64) -> Option<ButtonEvent>

Feed a debounced edge. Returns an event if one is resolvable purely from the edge (without waiting for a timeout).

pub fn poll(&mut self, now_ms: u64) -> Option<ButtonEvent>

Advance time without an edge. Returns an event if a timeout resolves one (long-press while held, or single/double after the inter-click gap).

pub fn next_deadline(&self) -> Option<u64>

Returns the absolute monotonic-millisecond deadline at which poll should next be called, if any.
