Identifies the kind of data stored in a segment.

Values 0x00 and 0xF0..=0xFF are reserved.

Variants

Invalid = 0

Not a valid segment (uninitialized / zeroed region).

Vec = 1

Raw vector payloads (the actual embeddings).

Index = 2

HNSW adjacency lists, entry points, routing tables.

Overlay = 3

Graph overlay deltas, partition updates, min-cut witnesses.

Journal = 4

Metadata mutations (label changes, deletions, moves).

Manifest = 5

Segment directory, hotset pointers, epoch state.

Quant = 6

Quantization dictionaries and codebooks.

Meta = 7

Arbitrary key-value metadata (tags, provenance, lineage).

Hot = 8

Temperature-promoted hot data (vectors + neighbors).

Sketch = 9

Access counter sketches for temperature decisions.

Witness = 10

Capability manifests, proof of computation, audit trails.

Profile = 11

Domain profile declarations (RVDNA, RVText, etc.).

Crypto = 12

Key material, signature chains, certificate anchors.

MetaIdx = 13

Metadata inverted indexes for filtered search.

Kernel = 14

Embedded kernel / unikernel image for self-booting.

Ebpf = 15

Embedded eBPF program for kernel fast path.

CowMap = 32

COW cluster mapping.

Refcount = 33

Cluster reference counts.

Membership = 34

Vector membership filter.

Delta = 35

Sparse delta patches.

Trait Implementations

impl Clone for SegmentType

fn clone(&self) -> SegmentType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SegmentType

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

Formats the value using the given formatter.

impl Hash for SegmentType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SegmentType

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

impl TryFrom<u8> for SegmentType

type Error = u8

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for SegmentType

impl Eq for SegmentType

impl StructuralPartialEq for SegmentType
