Struct ChromaDocument 

pub struct ChromaDocument {
    pub id: String,
    pub namespace: String,
    pub embedding: Vec<f32>,
    pub metadata: Value,
    pub document: String,
    pub layer: u8,
    pub parent_id: Option<String>,
    pub children_ids: Vec<String>,
    pub keywords: Vec<String>,
    pub content_hash: Option<String>,
    pub source_hash: Option<String>,
}

Fields

id: String

namespace: String

embedding: Vec<f32>

metadata: Value

document: String

layer: u8

Onion slice layer (1=Outer, 2=Middle, 3=Inner, 4=Core, 0=legacy flat)

parent_id: Option<String>

Parent slice ID in the onion hierarchy (None for Core slices)

children_ids: Vec<String>

Children slice IDs in the onion hierarchy

keywords: Vec<String>

Extracted keywords for this slice

content_hash: Option<String>

SHA256 hash of THIS chunk’s text. Used for chunk-level deduplication. Pre-v4 rows may transitionally store the source-text hash here; the /admin/backfill-hashes endpoint corrects them.

source_hash: Option<String>

SHA256 hash of the SOURCE document text (same value across all four onion layers from one source). Used for pre-index dedup so we never re-embed an already-ingested file. Optional for backward compatibility with v3 schemas — None means “unknown source provenance”.

Implementations

impl ChromaDocument

pub fn new_flat( id: String, namespace: String, embedding: Vec<f32>, metadata: Value, document: String, ) -> Self

Create a new document with default (legacy) slice values

pub fn new_flat_with_hash( id: String, namespace: String, embedding: Vec<f32>, metadata: Value, document: String, content_hash: String, ) -> Self

Create a new document with content hash for deduplication. Source hash is left empty — prefer new_flat_with_hashes so callers supply the source-document hash explicitly when they have it.

pub fn new_flat_with_hashes( id: String, namespace: String, embedding: Vec<f32>, metadata: Value, document: String, content_hash: String, source_hash: Option<String>, ) -> Self

Create a flat (legacy) document with both per-chunk and source hashes.

pub fn from_onion_slice( slice: &OnionSlice, namespace: String, embedding: Vec<f32>, metadata: Value, ) -> Self

Create a document from an onion slice

pub fn from_onion_slice_with_hash( slice: &OnionSlice, namespace: String, embedding: Vec<f32>, metadata: Value, content_hash: String, ) -> Self

Create a document from an onion slice with content hash for deduplication. Source hash is left empty — prefer from_onion_slice_with_hashes to preserve source provenance for pre-index dedup.

pub fn from_onion_slice_with_hashes( slice: &OnionSlice, namespace: String, embedding: Vec<f32>, metadata: Value, content_hash: String, source_hash: Option<String>, ) -> Self

Create an onion-slice document with both per-chunk and source hashes.

pub fn is_flat(&self) -> bool

Check if this is a legacy flat chunk (not an onion slice)

pub fn slice_layer(&self) -> Option<SliceLayer>

Get the slice layer if this is an onion slice
