Struct BounceFilter 

pub struct BounceFilter { /* private fields */ }

Holds the minimal state required for bounce filtering decisions.

This struct only stores the timestamp (in microseconds) of the last passed event for each key code and value combination.

Implementations

impl BounceFilter

pub fn new(ring_buffer_size: usize) -> Self

Creates a new BounceFilter with a specified ring buffer size.

The ring buffer stores the last ring_buffer_size passed events for debugging. If ring_buffer_size is 0, the buffer is not allocated and has no overhead.

pub fn check_event( &mut self, event: &input_event, debounce_time: Duration, skip_debounce: bool, ) -> EventInfo

Checks an incoming event against the debounce filter state.

Determines if the event is a bounce based on the debounce_time_us and the timestamp of the last passed event of the same type. Updates the internal state (last_event_us) only if the event passes. Also tracks the overall first and last event timestamps.

Arguments

• event: The input event to check.
• debounce_time: The debounce threshold as a Duration.

Returns

An EventInfo struct containing the result of the check and relevant timestamps.

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

Returns the total duration based on the first and last event timestamps seen. Returns None if no events were processed.

Trait Implementations

impl Default for BounceFilter

fn default() -> Self

Returns the “default value” for a type.
