Rust library implementing xor filters
Implementation of Xor Filters: Faster and Smaller Than Bloom and Cuckoo Filters in rust-lang, Journal of Experimental Algorithmics (to appear).
This package is a port from its golang implementation.
Open issues
- Serialize / Deserialize Xor8 type.
- Incrementally adding keys to a pre-built Xor8 instance.
