I find this style (Rust)) more readable end easier to extend: RangeInclusive::new(1, 10) .filter(|x| x % 2 == 0) .for_each(|x|{ println!("{}", x); }); (though you could write it the same way, for i in 1..=-10 { if .. { ..

For Rust, I am using Actix https://github.com/actix/actix-web . Without better definition of "secure" and "performance" there is no way to help you. Both of them are used and exposed publicly by num

If you want to get started quickly, Go. Better yet, Python or Ruby or Java, which have far more available frameworks and libraries. If you care about quality, performance and memory usage enough to invest more time into learning how to use

Uwagi is used for performance reasons only, once you have a language where its not a problem, it immediately goes away. I haven't seen anyone using it with Go for example.

Yes. Typically to serve several requests at the same time, you'd run multiple processes, each handling an at a time, and if you spend a lot of time waiting for io (database, some service call or slow client), you'll need to use a

I think the core issue here is not the quality of marketing , but simply the fact that it exists. People need some database, and nobody is spending money on advertising Postgres, so they don't know anything about it. Also Mongo wins by

No, you can use Rust without its stdlib. #![no_std] is a crate-level attribute that indicates that the crate will link to the core-crate instead of the std-crate. The libcore crate in turn is a platform-agnostic subset of the std crate whic

Its not a Rust problem, any project that mixes using string with passing them to C FFI and operating system API will need to handle those somehow differently. In Rust this is expressed with types and necessary checks/conversions are ve

This is false more often than not. Many programs taking user input will treat it as string, assuming specific encoding or compatibility with screen output/some api, at least in some code paths. For example if you print an error message
