Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Fleur – A bloom filter implementation in C
> There is also strange code like this loop https://github.com/hashlookup/fleur/blob/4ee2644a850381d928a... that jumped into my eye.
The line below that is worse:
strncpy(bloom_path , argv[optind], 128);
If you pass something >= 128 chars then bloom_path won't be null terminated. In general strncpy should never be used for copying strings.

Pros and Cons of Rust for Cybersecurity
But, due to the young ecosystem, Rust isn't often the best choice for the 2nd category. There are exceptions: while working on a ROP exploitation CLI tool, I was surprised to find the top 3 fastest x86-64 disassemblers are all written in Rust. But other languages just have more mature security ecosystems. Python in particular has some amazing libraries like scapy and bindings for yara.
What are some alternatives?
RedisBloom - Probabilistic Datatypes Module for Redis
signature-base - YARA signature and IOC database for my scanners and tools
awesome-yara - A curated list of awesome YARA rules, tools, and people.
a-ray-grass - a-ray-grass is a yara module that provides support for DCSO-format bloom filters in yara. In the context of hashlookup, it allows quickly discard known files "pour séparer le grain de l'ivraie"
scapy - Scapy: the Python-based interactive packet manipulation program & library. Supports Python 2 & Python 3.
xgadget - Fast, parallel, cross-variant ROP/JOP gadget search for x86/x64 binaries.
yara - The pattern matching swiss knife
disas-bench - X86 disassembler benchmark
Loki - Loki - Simple IOC and YARA Scanner
