Trait Embeddable 

pub trait Embeddable: Send + Sync {
    // Required methods
    fn key(&self) -> &str;
    fn content_hash(&self) -> String;
    fn embed_text(&self) -> &str;
    fn to_payload(&self) -> Value;
}

Domain type that can be stored in an EmbeddingRegistry.

Implement this trait for any struct that should be embedded and persisted in Qdrant. The registry uses key and content_hash to detect which items need to be re-embedded on each EmbeddingRegistry::sync call.

Required Methods

fn key(&self) -> &str

Unique string key used for point-ID generation and delta tracking.

fn content_hash(&self) -> String

BLAKE3 hex hash of all semantically relevant fields.

When this hash changes between syncs the item’s embedding is recomputed.

fn embed_text(&self) -> &str

Text that will be passed to the embedding model.

fn to_payload(&self) -> Value

Full JSON payload to store in Qdrant alongside the vector.

Must include a "key" field equal to Self::key() so EmbeddingRegistry can recover items on scroll.
