Struct VectorMappingEntry 

pub struct VectorMappingEntry {
    pub modalities: HashMap<Modality, ModalityVectors>,
    pub created_at: i64,
    pub version: u8,
}

Vector mapping entry for a single memory - MULTIMODALITY READY

Stores vector IDs for each modality separately, allowing:

• Text-only memories (current)
• Image-only memories (future)
• Multi-modal memories (text + image + audio)
• Cross-modal search via unified embeddings

Fields

modalities: HashMap<Modality, ModalityVectors>

Vector IDs per modality Key: Modality enum (serializes as string) Value: Vector IDs + metadata for that modality

created_at: i64

Timestamp when mapping was created (for debugging)

version: u8

Schema version for forward compatibility

Implementations

impl VectorMappingEntry

pub fn with_text(vector_ids: Vec<u32>) -> Self

Create a new mapping with text vectors (most common case)

pub fn text_vectors(&self) -> Option<&Vec<u32>>

Get text vector IDs (convenience method for current text-only usage)

pub fn all_vector_ids(&self) -> Vec<(Modality, u32)>

Get all vector IDs across all modalities (for deletion)

pub fn is_empty(&self) -> bool

Check if this entry has any vectors

pub fn add_modality(&mut self, modality: Modality, vector_ids: Vec<u32>)

Add vectors for a modality

pub fn with_image(self, vector_ids: Vec<u32>) -> Self

Future: Add image vectors

pub fn with_audio(self, vector_ids: Vec<u32>) -> Self

Future: Add audio vectors

pub fn with_video(self, vector_ids: Vec<u32>) -> Self

Future: Add video vectors
