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.

Why doesn't rust-analyzer reuse infrastructures of rustc?
In the last there was RLS that did exactly that. But the approach of rust-analyzer was found to be more performant.
-
[RFC] Generate Cabal files from TOML
LSP support seems to be lacking as well, at least rust doesn't seem to have Cargo.toml support? https://github.com/rust-lang/rls/issues/785
-
Referencing files in subfolders and difference between borrowing and C like references
apparently, it means that you're using the old RLS-based Rust plugin for VS Code, rather than the rust-analyzer plugin. You probably won't see a lot of people familiar with RLS's error messages.
-
friendly reminder for our vscode folks, use rust-analyzer
Why: The rust-analyzer extension integrates with rust-analyzer, an alternative language server for Rust. rust-analyzer tends to perform better and get less confused with your code as compared to RLS, which the Rust extension uses.

Show HN: Skruv – No-dependency, no-build, small JavaScript framework
I have tried writing websites with rust instead of JavaScript. Unfortunately, the tooling is just not there. More specifically, I am talking about wasm-bindgen, which provides two-way bindings. The problem with it is that since all the declarations are generated with build.rs, there is no autocompletion. Since I am spoiled by modern tooling, no autocompletion to me means not feasible pass demo stage. (https://github.com/rust-lang/rls/issues/1489)
Aside from the lack of autocompletion, passing rust closures to js land (DOM) is extremely janky as well. However, that might be caused by my lack of experience with rust.
(If you are curious, this is what I made: https://github.com/SCLeoX/non-grid-path-finder)

José Valim The Creator Of The Elixir Programming
Python the core devs don't care about tooling and they have IDE's, Java is an enterprise monolith so IDE's are the standard, Rust yes it is (https://github.com/rust-lang/rls), Elm I have no idea I don't use it.

Why did Prolog lose steam? (2010)
The Rust compiler uses a Prolog-like query language internally for type checking generic requirements and traits: https://github.com/rust-lang/chalk
-
Why doesn't rust-analyzer reuse infrastructures of rustc?
rust-analyzer already uses chalk (https://github.com/rust-lang/chalk) which should replace the current trait resolver.
-
Why use Rust on the backend? by Adam Chalmers
Well it's quite easy to come to that conclusion: The code compiles with rustc, which is currently the reference implementation. If rust-analyzer does not match rustc's behavior it's an issue in their implementation. That written it's not that easy to fix as it's related to how rust-analyzer resolves types/traits. rust-analyzer uses chalk for this, which is known to be incomplete/diverging from the RFC'ed behavior. Now one could argue that we can simplify diesel to the point where it works will with rust-analyzer/chalk, but that would result in basically removing core diesel features that exist way longer than rust-analyzer.

Why has functional programming become so popular in non-academic settings?
> Not all of those things work well in the real world. E.g. logic programming (prolog) is cool but ultimately never really caught on.
It does have its niches though. For example, there is a trait solver for Rust called Chalk that uses a Prolog-inspired language because trait bounds basically define a logic:
https://github.com/rust-lang/chalk
-
General mathematical expression analysis system
Maybe something in the prolog/datalog direction could be useful? Notably Rust has Chalk to help with trait resolution ("Chalk is a library that implements the Rust trait system, based on Prolog-ish logic rules.")
-
Useful lesser-used languages?
There has been work to implement part of the Rust typing logic in the Chalk Engine which uses a prolog-ish syntax to describe its rules.
-
Can you have a function return different types known at compile time
That's something Chalk is trying to tackle.
-
Compile time wins today
We probably will see all of them at some point -- polonius is a current effort to make the borrow checker accept more valid programs, in a way that also simplifies the logic and is probably a bit faster than the current NLL system, chalk is an attempt to do a similar thing for the trait system, and cranelift is a project that seeks to replace the LLVM codegen backend. But obviously, these are very large and complex projects that are gonna take some time.

What is the difference between associated types and generics?
Do Rust developers realize that? Oh, yes, absolutely, that's why we have this:
-
Question about Trait Bounds (from Rust for Rustaceans)
For me an attempt to write where HashMap: FromIterator and then use new and insert was totally bizzare because currently rustc is pretty primitive and doesn't do super-complex machinery needed to do what you want. Chalk may fix that one day, but it's nowhere near to being ready for inclusion into rustc thus I wouldn't even attempt to do what you tried to do… but that's not something you are supposed to know before reading this book!
