Struct FixedSizeEventBuffer 

pub struct FixedSizeEventBuffer<const N: usize> { /* private fields */ }

A fixed-size event buffer.

Implementations

impl<const N: usize> FixedSizeEventBuffer<N>

pub fn capacity(&self) -> usize

Returns the total number of events the event buffer can hold.

pub fn len(&self) -> usize

Returns the number of events in the event buffer.

pub fn is_empty(&self) -> bool

Returns true if the event buffer contains no events.

pub fn is_full(&self) -> bool

Returns true if the event buffer has no remaining capacity.

pub fn has_event_type(&self, event_type: EventType) -> bool

Returns true if this event buffer contains one or more events of the given event type.

pub fn clear(&mut self)

Clears the event buffer, removing all events and resetting the seen event types.

pub fn try_push(&mut self, event: Event) -> Option<Event>

Attempts to append an event to the back of the event buffer.

If the event buffer is full, Some is returned with the original event.

pub fn extract<F>(&mut self, predicate: F) -> impl Iterator<Item = Event>

where F: Fn(&Event) -> bool,

Extract events from the event buffer given a predicate function.

pub fn remove_if<F>(&mut self, predicate: F)

where F: Fn(&mut Event) -> bool,

Removes events from the event buffer if they match the given predicate.
