Struct SwipeAccumulator 

pub struct SwipeAccumulator { /* private fields */ }

The mid-swipe state machine shared by both gesture-capture paths: the HID++ thumb pad (openlogi-hid’s 0x1b04 raw-XY divert) and the OS-hook Middle/Back/Forward buttons (openlogi-agent-core’s CGEventTap). A gesture button’s hold accumulates travel; the instant the dominant axis commits a direction — after the button has been held GESTURE_HOLD_FOR_SWIPE, so a quick click whose cursor drifted doesn’t count — Self::accumulate returns that direction exactly once, like Logitech Options+. A hold that never commits is a plain click, reported by Self::end.

The two paths differ only in what identifies the held control (a ButtonId for the OS hook, a diverted CID for the thumb pad), so each owns that and embeds this for the shared travel logic. Keeping the logic in one place is deliberate: the two copies it replaced had already drifted apart (one resolved a swipe only on release), which mis-fired the click.

Implementations

impl SwipeAccumulator

pub fn begin(&mut self)

Begin a fresh hold, resetting the travel accumulator and commit state.

pub fn is_holding(&self) -> bool

Whether a hold is in progress (between Self::begin and Self::end), so callers can do rising/falling-edge detection without a second flag.

pub fn accumulate(&mut self, dx: i32, dy: i32) -> Option<GestureDirection>

Feed a pointer-move / raw-XY delta into the current hold. Returns Some(direction) exactly once per hold — the instant travel commits, and only after the hold passes GESTURE_HOLD_FOR_SWIPE — and None while still too short, already committed, or not holding.

pub fn end(&mut self) -> bool

End the current hold. Returns true when an in-progress hold ended without committing a swipe — the caller should fire the plain Click action — and false when a swipe already fired mid-motion, or when there was no hold to end (a stray release reports no click).
