}

One contiguous run of bytes in a synthesized virtual file.

Variants

Inline(Vec<u8>)

Generated framing/text bytes, fully materialized.

ArtImage

Image bytes the caller splices in from its art store; only the length is known here.

Fields

art_id: i64

len: BlobLen

BackingAudio

A run of the original backing file’s audio frames.

Fields

offset: u64

len: u64

OggAudio

A run of original audio pages served with each page’s sequence number shifted by seq_delta and its CRC recomputed. The byte length is unchanged (renumbering patches in place), so len equals the backing audio length.

Fields

offset: u64

len: u64

seq_delta: i64

OggArtSlice

A run of an embedded picture’s serialized bytes, served lazily from the art store (never stored in the layout). When base64, the run is len chars of base64(image) starting at output offset offset; otherwise it is len raw image bytes starting at raw offset offset. art_total is the raw image byte length (needed to clip the final base64 group).

Fields

art_id: i64

offset: u64

len: BlobLen

base64: bool

art_total: u64

BinaryTag

An opaque binary tag payload (e.g. an ID3 PRIV frame body or a FLAC APPLICATION block body) streamed from the DB at read time; only the length is known here. payload_id is the caller’s tags rowid handle.

Fields

payload_id: i64

len: BlobLen

Implementations

impl Segment

pub fn len(&self) -> u64

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for Segment

fn clone(&self) -> Segment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Segment

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

Formats the value using the given formatter.

impl Eq for Segment

impl PartialEq for Segment

fn eq(&self, other: &Segment) -> 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.
