PartEntry

Struct PartEntry 

Source
#[non_exhaustive]
pub struct PartEntry { pub bytes: Bytes, pub segment_number: u32, pub part_index: u32, pub duration: Duration, pub independent: bool, }
Available on crate feature std only.
Expand description

One LL-HLS partial segment (“part”) of the segment currently being written — RFC 8216bis §4.4.4.9’s independently-fetchable CMAF chunk, addressable by (segment_number, part_index) the way a client actually asks for one (_HLS_msn/_HLS_part, or a part-<seq>.<idx>.m4s URI). See The live-part log.

Does not reuse transmux::ll_hls::PartInfo whole, for the same reason SegmentEntry does not reuse transmux::ll_hls::SegmentInfo whole: PartInfo::bytes is Vec<u8>, and copying it into a Bytes here to get zero-copy fan-out (Zero-copy fan-out) would be exactly one copy per part, on the one path this module exists to keep copy-free; a caller publishing a part therefore builds a bytes::Bytes directly (e.g. from the encoder’s own output buffer) instead of routing through Vec<u8> first.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§bytes: Bytes

The part’s encoded bytes: a bare moof+mdat CMAF fragment (no styp). Bytes, not Vec<u8> — fan-out to every reader of this entry is a refcount bump, not a copy; see Zero-copy fan-out.

§segment_number: u32

The parent segment’s sequence number — matches SegmentEntry::sequence_number once that segment closes.

§part_index: u32

0-based index of this part within its parent segment.

§duration: Duration

This part’s duration, wall-clock.

§independent: bool

true when this part’s first sample is a sync sample, so it begins with an independently decodable frame (RFC 8216bis’s INDEPENDENT=YES).
