New APIs for JS, C, and Rust 🥳

New APIs for JS, C, and Rust 🥳

This release focuses on accelerating math with new SimSIMD capabilities, exposing exact search, parallel index construction, and parallel search to more runtimes!

• C: usearch_distance to compute the distance between 2 vectors.
• C: usearch_exact_search to perform exact search over strided matrices.
• JS: add, search, contains, count, and get now support batches and can run in parallel!
• JS: exactSearch to perform exact search over continuous matrices.
• Rust: export is similar to get but less error-prone.

Special thanks to @nairihar for his contributions on the JavaScript side, and to @weedge for contributions in Rust 🤗

Faster Exact Search 🎉

At the cost of using a bit more memory, I've made the exact search significantly faster.
LLM don't always need billion-scale vector search, but they often need to search through a small set of high-dimensional vectors.
I've added a benchmark you can run on your hardware to compare USearch against FAISS's exact search functionality.

$ python python/scripts/bench_exact.py --ndim 256 --n 100_000 --q 10 --k 100
USearch:  0.013957023620605469
FAISS:    0.04720497131347656

$ python python/scripts/bench_exact.py --ndim 256 --n 100_000 --q 10 --k 100 --half
USearch:  0.014386892318725586
FAISS:    0.08691692352294922

Even without hardware acceleration from SimSIMD, on the M2 Mac Book Pro:

• USearch performs 3.3x faster than FAISS on single-precision f32 vectors.
• USearch performs 6.1x faster than FAISS on half-precision f16 vectors.

In some settings, the difference may reach 10x. Below are samples for the 13th Gen Intel Core i9-13950HX x86 CPU:

$ python python/scripts/bench_exact.py --ndim 256 --n 100_000 --q 10 --k 100
USearch:  0.024287939071655273
FAISS:    0.2323017120361328

$ python python/scripts/bench_exact.py --ndim 256 --n 100_000 --q 10 --k 100 --half
USearch:  0.04021167755126953
FAISS:    0.20610713958740234

$ python python/scripts/bench_exact.py --ndim 256 --n 100_000 --q 100 --k 100
USearch:  0.12478017807006836
FAISS:    0.5975005626678467

$ python python/scripts/bench_exact.py --ndim 256 --n 100_000 --q 100 --k 100 --half
USearch:  0.423309326171875
FAISS:    0.7565422058105469

$ python python/scripts/bench_exact.py --ndim 256 --n 10_000 --q 10 --k 100 --half
USearch:  0.02945685386657715
FAISS:    0.11811184883117676

$ python python/scripts/bench_exact.py --ndim 256 --n 10_000 --q 100 --k 100 --half
USearch:  0.06946372985839844
FAISS:    0.15354132652282715

---

The script is located at python/scripts/bench_exact.py and has a few CLI parameters:

• --ndim - number of vector dimensions.
• --n - number of vectors in the dataset to search.
• --q - number of vectors to query among n.
• --k - number of closest neighbors to retrieve per query.
• --half - use half-precision.

For large q, FAISS works quite well - in such cases, it redirects the query to the linked BLAS implementation. But it means it supports only two metrics - L2 and inner product. With USearch exact search, you can still use all the same metrics as with usearch.index.Index class and provide custom JIT-ed CompiledMetric.

---

Thanks to @ebursztein, @guyrosin, and @vprelovac for suggesting the use case and spotting the issues!
Next step - expose exact search in JS, Rust, and Swift bindings 🎉
