Crate probabilistic_collections

probabilistic-collections-rs

probabilistic-collections contains various implementations of collections that use randomization to improve on running time or memory, but introduce a certain amount of error. The error can be controlled under a certain threshold which makes these data structures extremely useful for big data and streaming applications.

Usage

Add this to your Cargo.toml:

[dependencies]
probabilistic-collections = "*"

and this to your crate root if you are using Rust 2015:

extern crate probabilistic_collections;
