Let's list here crates that enhance Rust as a language.

It not "batteries" like in stdx, but Rust-specific crates for workarounds for various missing features and experimental ideals from non-accepted/postponed RFCs, or just hacky tricks.

The list is supposed to contain (mostly) crates that are internal to Rust, not ones for making Rust deal with "external world" like other languages bindings, file formats, protocols and so on.

Primary focus should be on crates that are not easy to find by conventional means (e.g. no algorithm name, format or protocol to search for).

Note that quality of the listed crates may vary from proof-of-concept to stable-and-widely-used.

Presentation on Const Generics as of 1.50.0 stable and 1.52.0-nightly

Challenges

• Beware no, or misleading, documentation
  • Nothing in Rust Book.
  • RFC https://rust-lang.github.io/rfcs/2000-const-generics.html and various issues rust-lang/rust#68436 have tips or examples, but many are invalid!
• Syntax may seem arbitrary:
  • Need ::< turbofish at some places, ordinary < elsewhere.
  • Need {...} curly brackets around some const generic parameter values, not around others.
  • Some error messages feel like going in circles.

Tips for Working With git Submodules

Cloning Repo with Submodules

Source: Stackoverflow :: Empty Git submodule folder when repo cloned

1. Use the --recursive flag:

    git clone https://github.com/aikiframework/json.git --recursive
   

   However if you cannot, as Github desktop app on clone does not use this flag, then do this after clone:

Why I don't use cider.

This is all personal opinion and a matter of taste. I'm putting it here because people have asked - I'm glad Cider exists and that a lot of people are obviously using it to great effect. This is not an attack on Cider or a an attempt to negate the experience of those who like it, just my own experience.

Also some of the critiques are more properly aimed at nRepl than Cider - I don't use nRepl either, in Emacs. For some reason I have fewer issues with it in Cursive (though I still do have some).

1. With Cider, there's too much "going on" between Emacs and Clojure. When something glitches, hangs, doesn't return a value, throws an excption, etc (as it does, multiple times a day), I don't know whether the problem is in Emacs, in the Cider client, the nRepl server, one of any of the default middlewares or in my actual program. I run Emacs in inferior lisp using lein trampoline -m clojure.main - if something goes wrong, it's either in Emacs (which is usually obvious) or my program. Mi
