Function faiss_sys::faiss_Index_range_search

pub unsafe extern "C" fn faiss_Index_range_search(
    index: *const FaissIndex,
    n: idx_t,
    x: *const f32,
    radius: f32,
    result: *mut FaissRangeSearchResult
) -> c_int

query n vectors of dimension d to the index.

return all vectors with distance < radius. Note that many indexes do not implement the range_search (only the k-NN search is mandatory).

@param index opaque pointer to index object @param x input vectors to search, size n * d @param radius search radius @param result result table
