Struct EventStreamBuilder 

pub struct EventStreamBuilder { /* private fields */ }

Builds an EventStream one event at a time, dropping events outside the sensor. The single construction path shared by readers and (future) transforms.

Implementations

impl EventStreamBuilder

pub fn new(width: usize, height: usize, timestamp_scale_ms: f64) -> Self

pub fn with_capacity( width: usize, height: usize, timestamp_scale_ms: f64, capacity: usize, ) -> Self

pub fn push(&mut self, x: u16, y: u16, timestamp: i64, polarity: bool) -> bool

Appends an event, returning false if it lies outside the sensor and was dropped. Callers that treat out-of-bounds events as errors inspect the result.

pub fn extend_from_stream(&mut self, stream: &EventStream)

Appends every event of stream, dropping any that fall outside this builder’s sensor.

The bulk counterpart of push, for the callers that join streams rather than generate them — concatenation, and the streaming writers that hand on a window at a time. When every event fits (the case for anything produced by a reader or the simulator, which cannot emit a coordinate its own sensor does not have) this is four extend_from_slice calls instead of a bounds check and four pushes per event; the scan that establishes that is two comparisons per event and vectorises.

pub fn reserve(&mut self, additional: usize)

Reserves room for additional more events across every column.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn build(self) -> EventStream
