Trait VectorProvider 

pub trait VectorProvider {
    // Required method
    fn get_vector(&self, id: VectorId) -> Cow<'_, [f32]>;

    // Provided methods
    fn is_deleted(&self, id: VectorId) -> bool { ... }

}

Trait for providing vector data by ID.

Required Methods

fn get_vector(&self, id: VectorId) -> Cow<'_, [f32]>

Returns the vector data for a given ID.

Provided Methods

fn is_deleted(&self, id: VectorId) -> bool

Returns true if the vector is marked as deleted.

fn get_quantized_vector(&self, id: VectorId) -> Option<&[u8]>

Returns the quantized vector data for a given ID, if available.

Returns

• Some(&[u8]) - If the provider supports direct quantized access.
• None - If not supported or data is not quantized.

fn quantize_query<'a>( &self, query: &[f32], output: &'a mut Vec<u8>, ) -> Option<&'a [u8]>

Quantizes a query vector into the provided output buffer.

Arguments

• query - The query vector in f32.
• output - buffer to write quantized data into.

Returns

• Some(&[u8]) - The quantized slice (borrowed from output).
• None - If quantization is not supported.
