Struct SiftDataset 

pub struct SiftDataset {
    pub base: Vec<Vec<f32>>,
    pub queries: Vec<Vec<f32>>,
    pub ground_truth: Vec<Vec<u32>>,
    pub dim: usize,
}

One full SIFT-family dataset: base vectors, query vectors, per-query ground-truth neighbour ids, and the shared dimensionality.

base[i] is the i-th base vector — i is also the row-index ID used in crate::build_index_from_base and the value stored in the .ivecs ground-truth entries.

Fields

base: Vec<Vec<f32>>

The base vectors used to build the index under test.

queries: Vec<Vec<f32>>

The query vectors against which recall and latency are measured.

ground_truth: Vec<Vec<u32>>

Per-query exact top-k neighbour ids (ids index into base).

dim: usize

The dimensionality every base and query vector shares.

Trait Implementations
