Best path to learn rust
You absolutely must write programs, preferably using tests to ensure you are creating correct and reproducible code. May I suggest starting with my book, Command-Line Rust (O'Reilly, 2022). All the code/data/tests are in https://github.com/kyclark/command-line-rust Note that there are branches showing how to use the 4.x version of clap (command-line argument parser) rather than the 2.33 that was current when the book was published.

How to start learning a systems language
I think the best way to start learning a programming language is to write lots of small programs that you probably already know. Rust is a perfect command-line language, so I think it makes sense to start by implementing simple programs like "head" and "grep." I also think one should always learn to write and run tests, so I present my GitHub repo of inputs and tests you might like to use to write 14 such standard Unix command-line utilities: https://github.com/kyclark/command-line-rust If you want guidance on the language, I wrote a book called Command-Line Rust (O'Reilly, 2022) that explains all this code. One caveat is that the "clap" (command-line argument parser) module was at 2.33 when I published but is now v4, so you should look at the appropriate branches for versions of the programs that use the "builder" and "derive" patterns for that module. Or just use any old command-line parser you like as there's no requirement to use "clap." Best of luck to you!

What is the best way to learn Rust from a complete beginner programmer?
You must write programs in a language in order to learn it. I also firmly believe that learning how to write and run tests is critical to learning any language. I wrote Command-Line Rust (O'Reilly, 2022) for the beginner (in Rust, at least) and with a focus on writing and testing small programs from very simple "Hello, world!" and getting increasingly more complex. You can look at https://github.com/kyclark/command-line-rust for the code/inputs/tests. Best of luck!

Stuck at 4.3 of the rust book. It's so hard for me.
I'm the author of Command-Line Rust (O'Reilly, 2022), which I wrote to introduce the language slowly to beginners by writing and testing short, focused programs. You can look over the code/tests/data at https://github.com/kyclark/command-line-rust. Note that there are branches that show the same programs using a more recent version of the "clap" crate.

How do i get started with rust as my first language. I need tips and useful advice from rustians thanks.
I wrote Command-Line Rust (O'Reilly, 2022) to guide beginners in the language. You are challenged to write small functions and programs using tests to verify that everything is correct. You can look over the code and tests at https://github.com/kyclark/command-line-rust. Best of luck in your journey!

How to Practice and Learn Rust for Production Level Code?
I like to suggest that students write programs they already know (or at least understand). For instance, you probably understand that head shows the first few lines of a text file, and you probably can already implement some version of that in one or two languages you know. Try that in Rust. I wrote 14 BSD/GNU command-line utilities in Rust for learning purposes. I wouldn't consider these high-performance/production programs as they are tailored to learning the language. I also stress how to test programs, so there are tests and inputs you can use to verify your programs match the output of the original programs (or you can modify these to suit your own tastes for how you would like them to work). https://github.com/kyclark/command-line-rust

Error handling in a CLI app
Here are some more examples you may or may not find useful: https://github.com/kyclark/command-line-rust I tend to have a main() that calls a library's run() function that returns a Result and then exit with a nonzero code and error message on a failure.

Need a new args parser

An alternative to clap but with a stable API?
Maybe pico-args then?

Immediately off the top of your head what is the best Rust CLI library.
If I forget to get around to it, would you mind poking RazrFalcon/pico-args about adding it to the comparison chart? I really like using that thing as something I can link people to with just a quick explanation of that particular trade-off.

Best CLI arg parser for use in Rust to port from Perl with Getopt::Long?
If fewer dependencies is better, you can't get much fewer than pico-args, which has zero dependencies.

Creating an Argparse library [feedback would be appreciated]
You might also want to check out pico-args, Gumdrop, and lexopt to see if any of them meet your needs.

New:`cargo-fuzzcheck` 0.5.0 and a series of decent, fast-to-compile crates to replace `syn`, `quote`, `serde-json`, and `toml-rs`
For example, I'd love to go from StructOpt to Gumdrop for parsing command-line arguments and cut my compile times and output size by an order of magnitude, but Gumdrop uses String internally, which means it'll panic if it encounters a Windows path with un-paired surrogates or a mojibake'd posix path... some of which I actually have.
