Struct Chapter 

pub struct Chapter {
    pub id: u64,
    pub start: Timestamp,
    pub end: Timestamp,
    pub title: Option<String>,
    pub language: Option<String>,
}

One chapter / cue point inside a container.

Containers that only carry a start time (Vorbis-comment chapters, DVD IFO PGCs without explicit end times) set end == start. The id field is whatever the container uses internally — MKV’s ChapterUID, MP4 chapter track sample index, or a synthesised counter for formats without a stable ID.

Fields

id: u64

Container-native chapter identifier. Stable across demuxer re-opens of the same file but not comparable across different containers.

start: Timestamp

Chapter start time. The Timestamp’s time base is whatever the demuxer reports; consumers should rescale to a common base before comparing chapters from different sources.

end: Timestamp

Chapter end time. Equal to start when the container does not store an explicit end (the next chapter’s start is the implicit end in that case).

title: Option<String>

Display title in the chapter’s primary language, if present.

language: Option<String>

BCP-47 / ISO 639 language tag for the title ("en", "jpn", …) when the container labels it. None means “unspecified” — not “neutral”.

Trait Implementations

impl Clone for Chapter

fn clone(&self) -> Chapter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Chapter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Chapter

fn eq(&self, other: &Chapter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
