Struct TimelineIndex 

pub struct TimelineIndex { /* private fields */ }

The lazily expanded timeline.

Implementations

impl TimelineIndex

pub fn build( timeline: &SegmentTimeline, start_number: u64, period_end_ticks: Option<u64>, ) -> Result<Self, AddressError>

Build the run table.

period_end_ticks is on the media timeline (PTO + (PEwc - PSwc)), used by a trailing negative @r; None makes such a run a single segment.

Errors

AddressError for a non-increasing @t/@n, an oversized or overflowing timeline, or an unsupported feature.

pub fn len(&self) -> u64

Number of segments.

pub fn is_empty(&self) -> bool

Whether the timeline has no segment.

pub fn segment(&self, index: u64) -> Option<TimelineSegment>

Segment at zero-based index.

pub fn index_at_or_before(&self, time: u64) -> Option<u64>

Index of the last segment whose start is at or before time (media timeline ticks); None when time precedes the first segment.

pub fn count_up_to_number(&self, max_number: u64) -> u64

How many segments have a number at or below max_number (@endNumber: a segment numbered above it is invalid, 5.3.9.5.3).

pub fn iter(&self) -> impl Iterator<Item = TimelineSegment> + '_

The segments in order (lazy).
