How does Rust compare to Haskell/OCaml in 2026 ?!

In terms of things like

• Tooling
• Standard Library
• Documentation
• Production Use
• Type System
• Performance
• Pragmatic
• Compile Errors

I ask so because I have tried out Haskell and SML, but writing any IO/Network software in them is really complex. + I don't understand Haskell's IO Monad and etc, and what makes it pure and why not impure.I have tried quite hard. but coming to Rust, I really don't need the low level interface and I okay with a GC. With Haskell I am super comfortable untill the `IO` monad comes into the code, usually for things like AdventOfCode and etc.

Compile Errors

Why installing a formatter took so long ? Did I do something wrong ?

npm i -g, go get , are really fast

the command I used cabal install ormolu

my env cabal-install version 3.14.2.0 The Glorious Glasgow Haskell Compilation System, version 9.14.1 Host: Mac15,6 OS: macOS 26.5 25F71 arm64 Kernel: 25.5. CPU: Apple M3 Pro

I faced similar issue when I tried installing pandoc.

i am looking for a library to compute md5hash from a given string or a file. what library is right for it ? there seem to be multiple like

crypton cryptonite crypto-api

Isn't there a standard library like text or containers ?

I have tried Emacs (doom-emacs) and VSCode, both suffer from 2 different Issues. I do a hover on symbol String, and it gives the documentation for it in a popup. When I click on Source or Documentation, there are different things

In Emacs the link is file:///Users/krishnashagarwal/.ghcup/ghc/9.12.2/share/doc/ghc-9.12.2/html/libraries/ghc-internal-9.1202.0-7717/src/GHC.Internal.Base.html#t:String , which when clicked doesn't really do anything, instead of searching online, it tries to search locally and FAILS

In Vscode, the link is https://hackage.haskell.org/package/ghc-internal-9.1202.0-7717/docs/GHC-Internal-Base.html#t:String Which goes on internet, but goes to Page Not Found
