Coldsnap-rust - Rust Snapshot Fuzzer Example

Welcome to coldsnap! This example was inspired by @gamozolabs love for snapshot fuzzing and based on @h0mbre_ blog Fuzzing Like A Caveman 4

This example is a 1-to-1 port of https://github.com/defparam/Coldsnap into Rustlang, Please read the README.md of the original Coldsnap repo to get an idea of what this example does.
