Introduction

If you are familiar with Java's generics, and are coming to Rust, you might be lead to assume that its generics are working the same way.

However, due to the different type systems, and different implementation details, there are quite a few differences between generic code in both languages.

This document tries to give a short summary about those differences:

General Background and Overview

Probabilistic Data Structures for Web Analytics and Data Mining : A great overview of the space of probabilistic data structures and how they are used in approximation algorithm implementation.

Philippe Flajolet’s contribution to streaming algorithms : A presentation by Jérémie Lumbroso that visits some of the hostorical perspectives and how it all began with Flajolet
Approximate Frequency Counts over Data Streams by Gurmeet Singh Manku & Rajeev Motwani : One of the early papers on the subject.

	Might be up for debate or just plain wrong. Just some notes I scribbled down some time ago.
