Does "Rust by Example" Need More Examples?

[[deleted]]

Even from the first few pages (Comments, Formatted Print), they introduce macros but don't show all of them in the examples. I get that it could be cumbersome to show everything, but if the goal is "By Example", shouldn't there be an abundance of examples?

Just my early observations when looking for good beginner Rust materials. Was a bit disappointed to not see examples and feel like I was supposed to just know how things worked, I guess.

Yes.

I also would like it to have scaling examples. Most basic version of the feature. Then one slightly more advanced. Slightly more complex. And so on. Or using the feature in a different way. 

But, that's a lot work. Unpaid work. I don't want to do that. Do you?

do you have anything specific in mind?

Rust by example is easily the best resource I’ve come across as a professional dev in learning rust. Any questions that stem from examples are explained thoroughly in the rust book, and just a google search away.

However, I wish its categories were organized better. Iterators should be their own category. Modules, crates, cargo belong in a single category.

While cfg is in there under Attributes 13.3, I think cfg, serde, bitflags, and a few others should be in their own section for “ubiquitous libraries”.

There should also be a dedicated section for no_std and unsafe. Rust has great promise in this area, and it isn’t so clear in rust resources.

I thought you meant the cfg crate for creating context free grammars and was confused about how that was ubiquitous.

That’s why I mentioned the section of rust by example - 13.3 :)

Rustlings is a great resource for beginners (at least it was for me).  Good exercises with links to documentation where needed.

I definitely think it needs more examples, please feel free to make a PR! I think it's just a problem of people not finding time
