Struct ChapterInfo 

pub struct ChapterInfo { /* private fields */ }

Information about a chapter within a media file.

Chapters are discrete, named segments within a container (e.g., a chapter in an audiobook or a scene in a movie). Each chapter has a start and end time, and optionally a title and other metadata tags.

Construction

Use ChapterInfo::builder() for fluent construction:

use ff_format::chapter::ChapterInfo;
use std::time::Duration;

let chapter = ChapterInfo::builder()
    .id(0)
    .title("Intro")
    .start(Duration::ZERO)
    .end(Duration::from_secs(30))
    .build();

Implementations

impl ChapterInfo

pub fn builder() -> ChapterInfoBuilder

Creates a new builder for constructing ChapterInfo.

pub fn id(&self) -> i64

Returns the chapter ID.

pub fn title(&self) -> Option<&str>

Returns the chapter title, if available.

pub fn start(&self) -> Duration

Returns the chapter start time.

pub fn end(&self) -> Duration

Returns the chapter end time.

pub fn time_base(&self) -> Option<Rational>

Returns the chapter time base, if available.

pub fn metadata(&self) -> Option<&HashMap<String, String>>

Returns the chapter metadata tags (excluding “title”), if any.

pub fn has_title(&self) -> bool

Returns true if the chapter has a title.

pub fn duration(&self) -> Duration

Returns the chapter duration (end − start).

Uses saturating subtraction so that malformed chapters where end < start return Duration::ZERO instead of panicking.
