Struct IdDictionaryValue 

pub struct IdDictionaryValue {
    pub vector_id: u64,
}

IdDictionary value storing the internal vector ID for an external ID.

The key for this record is IdDictionaryKey { external_id }, which uses TerminatedBytes encoding to preserve lexicographic ordering of external IDs.

Value Layout (little-endian)

┌────────────────────────────────────────────────────────────────┐
│  vector_id:  u64  (8 bytes, little-endian)                     │
└────────────────────────────────────────────────────────────────┘

Usage

• Insert: Look up external ID → if exists, upsert; else allocate new internal ID
• Get by external ID: Point lookup to resolve external → internal mapping
• Get by internal ID: Use VectorMeta which stores the reverse mapping

Fields

vector_id: u64

Internal vector ID (system-assigned, monotonically increasing).

This ID is used in VectorData, VectorMeta, posting lists, and metadata indexes. It’s allocated from SeqBlock using block-based allocation for crash safety.

Implementations

impl IdDictionaryValue

pub fn new(vector_id: u64) -> Self

pub fn encode_to_bytes(&self) -> Bytes

pub fn decode_from_bytes(buf: &[u8]) -> Result<Self, EncodingError>

Trait Implementations

impl Clone for IdDictionaryValue

fn clone(&self) -> IdDictionaryValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdDictionaryValue

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

Formats the value using the given formatter.

impl PartialEq for IdDictionaryValue

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