Fuzzcheck (a structure-aware Rust fuzzer)
Fuzzcheck is a structure-aware fuzzer for rust. "Fuzzing" means feeding large amounts of data into a program and checking for crashes (Fuzzcheck also checks to make sure that all the properties your program should uphold – e.g. a sorting algorithm applied to a list of n items should always return a list of n items – are upheld). Fuzzcheck is an "evolutionary" fuzzer – this means that it generates a set of random inputs, sees what percentage of the program is executed for each input, and keeps inputs which have high levels of percentage of program executed. It then "mutates" these inputs – whereas fuzzers such as AFL/Hongfuzz/etc mutate raw bytes in place (e.g. they swap bytes at different positions, or insert a random byte at a given position to generate inputs similar to the chosen "high coverage" inputs), Fuzzcheck works directly on the Rust types (so it might swap the order of two items in a vec, or randomly insert a new item). It's a really powerful tool for finding lots of bugs.

fuzzcheck 0.9 release - run coverage-guided fuzz tests alongside your regular unit tests + code coverage visualiser + new online guide and improved documentation
If you want help with Win support (issues/8) maybe post it here to get it added to TWIR.

What's everyone working on this week (43/2021)?
I am working on a code coverage viewer for my fuzzer (fuzzcheck). I described what I've done so far in this issue and I am hoping to release the first version within two weeks.

What's everyone working on this week (31/2021)?
The implications for my fuzzer, fuzzcheck, are huge! Compiling fuzz tests is a lot easier. There should be no more need to create a separate fuzz folder, fuzz tests can be regular #[test] functions, private implementation details can be fuzz-tested as well, rust-analyser works as expected, documentation can be easily generated, etc. I can also attach a human-readable coverage report to every test case :)

What's everyone working on this week (30/2021)?
Since I graduated, I have had a lot more time to work on fuzzcheck. I am trying to flesh it out, test it, and document it for a new release. It has always felt a bit rushed/experimental and now I am hoping to make it into something solid. I have also played with an egui interface for it, to visualise the tested code coverage, understand how the fuzzer’s decisions are made, and also to interactively tweak the fuzzer’s behaviour. It's a lot of work but it's slowly all coming together! :)

What's your favourite under-rated Rust crate and why?
fuzzcheck-rs is really cool. It combines property-testing with fuzzing, getting the nice, structured nature of the former, and the coverage-driven search of the latter, but it works by mutating the structure directly instead of going through a bit string. So if you have a binary tree, going from A(B, C) to A(C, B) can be a single mutation away if that makes sense in your use case, instead of being arbitrarily far away in the bitstring approach.

What are some common verbose code patterns in rust and unique ways to reduce the said verbosity?
Take a look at the strum crate. https://crates.io/crates/strum

Published my first Crate today to map Environment Variables to Enums
I would be use something like https://github.com/Peternator7/strum if I need map string to enum and serde is not the option.
-
Two-way alternative to enum_kinds crate?
Looks like proper support for this in strum has been proposed.
-
Best way of associating enums with values?
This crate can generate an iterator for you using a macro https://github.com/Peternator7/strum

Hey Rustaceans! Got a question? Ask here (4/2023)!
The strum crate is also good for removing this kind of boilerplate, and worth checking out!

What are some less popular but well-made crates you'd like others to know about?
strum is among my favorite crates to recommend. Favorites of this crate include EnumProperty and EnumIter

What's everyone working on this week (45/2022)?
I released my first crate that provides a derive macro to easily obtain a name of a current variant in an enum as a string. I did it mostly to learn about procedural macros and the process of releasing a crate. I then found out there is strum which does this and much more. Nonetheless, I learned a lot and I found couple of nice tools like ```cargo-release and git-cliff.

Hey Rustaceans! Got a question? Ask here! (33/2022)!
I used https://crates.io/crates/strum to iterate over the enum variants, otherwise you'd have to hardcode the list of variants and wouldn't gain anything.

Questions about enums
If you chose to go with the "derive a trait" route the strum crate might be what you're looking for. It lets you use derive to add information about variant count, discriminants or even iterators over variants to an enum.
