Instant Distance: fast HNSW indexing

Build status License: MIT License: Apache 2.0

Instance Distance is a fast pure-Rust implementation of the Hierarchical Navigable Small Worlds paper by Malkov and Yashunin for finding approximate nearest neighbors. This implementation will power the InstantDomainSearch.com backend services used for word vector indexing.
