Struct symphonia_core::formats::util::SeekIndex

pub struct SeekIndex { /* private fields */ }

A SeekIndex stores SeekPoints (generally a sample or frame number to byte offset) within a media stream and provides methods to efficiently search for the nearest SeekPoint(s) given a timestamp.

A SeekIndex does not require complete coverage of the entire media stream. However, the better the coverage, the smaller the manual search range the SeekIndex will return.

Implementations

impl SeekIndex

pub fn new() -> SeekIndex

Create an empty SeekIndex

pub fn insert(&mut self, ts: u64, byte_offset: u64, n_frames: u32)

Insert a SeekPoint into the index.

pub fn search(&self, frame_ts: u64) -> SeekSearchResult

Search the index to find a bounded range of bytes wherein the specified frame timestamp will be contained. If the index is empty, this function simply returns a result indicating the entire stream should be searched manually.

Trait Implementations

impl Default for SeekIndex

fn default() -> SeekIndex

Returns the “default value” for a type.
