strum VS heed

Take a look at the strum crate. https://crates.io/crates/strum

I would be use something like https://github.com/Peternator7/strum if I need map string to enum and serde is not the option.

Looks like proper support for this in strum has been proposed.

This crate can generate an iterator for you using a macro https://github.com/Peternator7/strum

The strum crate is also good for removing this kind of boilerplate, and worth checking out!

strum is among my favorite crates to recommend. Favorites of this crate include EnumProperty and EnumIter

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.

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.

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.

At Meilisearch we are currently trying to add a better error handling in heed v0.20, our LMDB key-value store wrapper. Unfortunately, when there are a lot of generics it can become harder to play with…

There are issues and pull requests but I advise you to look at the milli folder in the Meilisearch repository, it’s where all the logic is done. We extensively use RoaringBitmaps, heed the LMDB wrapper and grenad when indexing.

I’ll continue to introduce new features and new safety guards until v0.20.0. Can you tell me more about your project? Or is it private?

LMDB support multiple readers and one writer at the same time. It is ensured by the library. Note that LMDB is a key-value store. You can use the heed library which is the most maintained Rust wrapper.

Note that heed is ensuring that you are not trying to use transactions, databases and environments in the right way. I have added much more work in that regard in the important update that I am working on too!

I am currently working on exposing the new LMDB encryption feature from heed the safe LMDB wrapper with the help of the Cryptography community.

Have you considered heed or even sanakirja?

rkv hasn't been updated for a while. I recommend using heed - https://docs.rs/heed

For wrappers around LMBD, I'd recommend RKV or Heed https://github.com/mozilla/rkv https://github.com/Kerollmops/heed
