Struct MemorySliceSource 

pub struct MemorySliceSource { /* private fields */ }

A SliceSource backed by an already-loaded stream — the universal fallback for formats without native random access (npz/txt/bag today). Slicing is entirely in-RAM, so open() returns a working handle for every supported format from day one.

Implementations

impl MemorySliceSource

pub fn new(stream: EventStream) -> Self

Trait Implementations

impl SliceSource for MemorySliceSource

fn sensor_size(&self) -> (usize, usize)

fn timestamp_scale_ms(&self) -> f64

fn n_events(&self) -> usize

Total events in the file.

fn time_span(&self) -> (i64, i64)

(t_min, t_max) in microseconds across the whole file; (0, 0) when empty.

fn slice_index(&self, i0: usize, i1: usize) -> Result<EventStream, IoError>

Events whose index lies in [i0, i1) (clamped to the file).

fn slice_time(&self, t0: i64, t1: i64) -> Result<EventStream, IoError>

Events whose timestamp (µs) lies in the half-open window [t0, t1).
