The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

::lending-iterator — Lending/streaming Iterators on Stable Rust (and a pinch of HKT)
Luckily there is a workaround to emulate such a definition, which dtolnay discovered and explained here: https://github.com/dtolnay/case-studies/tree/b9802f6df8dc8e54970b83fb9af6df923b46abf5/unit-type-parameters.

Hey Rustaceans! Got a question? Ask here! (17/2022)!
I think they are talking about this one trick which the devs don't want you to know about. Note that while it looks like specialization, it works only in a few very limited cases and is quite fragile, so it's a hack, not a substitute for the real feature.
-
Any good resources for learning Rust macros?
Also I suggest his case studies repo since you are looking at what is possible: https://github.com/dtolnay/case-studies
-
What are some creative/advanced uses of macro_rules?
/u/dtolnay has a great case studies repository.

Hey Rustaceans! Got an easy question? Ask here (29/2021)!
Once you have the basics down, read dtolnay's case studies. They show how to do advanced stuff with easy macros.

println use `Debug` if argument is not `Display`
If you were writing your own println macro, you might be able to get away with this kind of hack: https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md
-
Hey Rustaceans! Got an easy question? Ask here (11/2021)!
You can use "Autoref-based stable specialization" or use/mimic the impls crate.

Why I gave up on Rust (for now)
With a subset of specialization likely riding the trains soon and a workaround available, why would you give up?
-
Hey Rustaceans! Got an easy question? Ask here (10/2021)!
this works since values and types are in different namespaces (see: Rusts Universes or dtolnay's Case Study about "Unit struct with type parameters")
-
Hey Rustaceans! Got an easy question? Ask here (53/2020)!
To do this with traits you would need specialization but since you are using macros you should be able to use "Autoref-based stable specialization". Here is a playground which uses the latter approach to implement the wanted macro without using any nightly features.

Rust is showing a lot of promise in the DataFrame / tabular data space
[arrow2](https://github.com/jorgecarleitao/arrow2) and [parquet2](https://github.com/jorgecarleitao/parquet2) are great foundational libraries for and DataFrame libs in Rust.

::lending-iterator — Lending/streaming Iterators on Stable Rust (and a pinch of HKT)
This is so freaking life-saving! - we have been using StreamingIterator and FallibleStreamingIterator in libraries (arrow2 and parquet2) and the existing landscape is quite confusing for new users!
- Anda para aqui alguém a brincar com Rust (linguagem)?

Parquet2 0.9 released (and a request for feedback)
Thanks a lot for your feedback. Based on it I am proposing the following change: https://github.com/jorgecarleitao/parquet2/pull/78
-
parquet2 0.3.0, with native support to read async
release on github.
What are some alternatives?
