Struct FlatVectorData 

pub struct FlatVectorData {
    pub dim: usize,
    pub vectors: Vec<Vec<f32>>,
    pub doc_ids: Vec<(u32, u16)>,
}

Flat vector data for brute-force search (accumulating state)

Fields

dim: usize

vectors: Vec<Vec<f32>>

doc_ids: Vec<(u32, u16)>

Document IDs with ordinals: (doc_id, ordinal) pairs Ordinal tracks which vector in a multi-valued field

Implementations

impl FlatVectorData

pub fn estimated_memory_bytes(&self) -> usize

Estimate memory usage

pub fn to_binary_bytes(&self) -> Vec<u8>

Serialize to compact binary format.

Format: magic(4) + dim(4) + num_vectors(4) + vectors(dimn4) + doc_ids(n*6) Much more compact than JSON and avoids intermediate allocations.

pub fn serialize_binary_from_flat( index_dim: usize, flat_vectors: &[f32], original_dim: usize, doc_ids: &[(u32, u16)], ) -> Vec<u8>

Serialize directly from flat f32 storage (avoids Vec<Vec> intermediate).

flat_vectors is contiguous storage of dim*n floats. original_dim is the dimension in flat_vectors (may differ from index_dim for MRL).

pub fn from_binary_bytes(data: &[u8]) -> Result<Self>

Deserialize from binary format.
