Struct Chunk 

pub struct Chunk {
    pub id: String,
    pub document_id: String,
    pub chunk_index: i64,
    pub text: String,
    pub hash: String,
}

A chunk of a document’s body text, stored in the chunks table.

Documents are split into chunks by the crate::chunk module to enable granular retrieval and embedding. Each chunk has:

• A deterministic UUID (derived from document_id + chunk_index)
• A contiguous chunk_index starting at 0
• A SHA-256 hash of its text content, used by the embedding pipeline to detect when re-embedding is needed (staleness detection)

Fields

id: String

UUID v4 primary key.

document_id: String

Foreign key to the parent Document.

chunk_index: i64

Zero-based index within the document’s chunk sequence.

text: String

Chunk text content.

hash: String

SHA-256 hash of text, used for embedding staleness detection.
