@jonas Besides the other answers:

If you are looking for a way to store multiple bool values in a memory efficient way, have a look at bitvec crate:

https://docs.rs/bitvec/latest/bitvec/

"[bitvec] specializes standard-library data structures (slices, arrays, and vectors of bool) to use _one-bit-per-bool storage_[...]"

"[it] brings the capabilities of C++’s compact bool storage and Erlang’s decomposable bit-streams to Rust" - from their docs

winnow - Making parsing a breeze:

https://github.com/winnow-rs/winnow

winnow is a parser combinator library written in Rust that started as a fork of #nom.

Not sure yet, if I should migrate from nom 4.* to #winnow or #chumsky. I really do like the good error recovery and parsing capabilities for PEGs of chumsky.🥰

It's here! 🎉

Announcing match-commutative | A #Rust macro that helps matching on patterns commutatively, reducing the use of duplicated patterns. ✨

This can be useful, if you need to match on `(operant1, op, operant2)`, where `op` builds a commutative relation between `operant1` and `operant2`.

Please see the docs for the actual use case and an example:

https://docs.rs/match-commutative

Tagging @rjacobson and @tuck, because they've been interested in this. 😉

#Rust library to compare strings (or any sequences). 25+ algorithms, pure Rust, common interface, #Unicode support.

https://github.com/life4/textdistance.rs

Based on popular and battle-tested textdistance #Python library (and written by the same author).

Apparently, it also takes algorithms from the #talisman #JavaScript library, which I wished for to be written in Rust.

welds - An async #ORM written in #Rust using the #sqlx framework.

You can even drop down to low-level sqlx queries, in case you need it:

As Jon said, HashSet and HashMap iteration ordering is random.

If you need to iterate in insert order, you can use a crate called indexmap by @bluss

https://lib.rs/crates/indexmap

It provides Set and Map data structures.

Ok, this looks really useful:

mirror-mirror | Powerful reflection library for #Rust (by EmbarkStudios)

Especially, because Rust is known to lack capabilities of reflection.

And what a cool name! 😅
