Apache® DataSketches™ Core Rust Library Component

This is the core Rust component of the DataSketches library. It contains a subset of the sketching algorithms and can be accessed directly from user applications.

Note that we have parallel core library components for Java, C++, Python, and Go implementations of many of the same sketch algorithms:

Please visit the main DataSketches website for more information.
