Which is one of the reasons why Rust is considered to be targeting C++'s developers. C++ devs already have the Stockholm syndrome needed to tolerate the tooling.

Rust's compilation is slow, but the tooling is just about the best that any programming language has.

    Slow compared to what? I’m still scraping my head at this. My cargo builds are insanely fast, never taking more than a minute or two even on large projects. The only ahead of time compiled language I’ve used with faster compilation speed is Go, and that is a language specifically designed around (and arguably crippled by) the requirement for fast compilation. Rust is comparable to C compilation, and definitely faster than C++, Haskell, Java, Fortran, Algol, and Common Lisp.

    How good is the debugger? "edit and continue"? Hot reload? Full IDE?

    I don't know enough Rust, but I find these aspects are seriously lacking in C++ on Linux, and it is one of the few things I think Windows has it better for developers. Is Rust better?

      > debugger

      I've only ever really used a debugger on embedded, we used gdb there. I know VS: Code has a debugger that works, I'm sure other IDEs do too.

      > edit and continue

      Hard to do in a pre-compiled language with no runtime, if you're asking about what I think you're asking about.

      > Hot reload

      Other folks gave you good links, but this stuff is pretty new, so I wouldn't claim that this is great and often good and such.

      > Full IDE

      I'm not aware of Rust-specific IDEs, but many IDEs have good support for Rust. VS: Code is the most popular amongst users according to the annual survey. The Rust Project distributes an official LSP server, so you can use that with any editor that supports it.

Also modern c++ with value semantics is more functional than many other languages people might come to rust from, that keeps the borrow checker from being as annoying. If people are used to making webs of stateful classes with references to each pther. The borrow checker is horrific, but that is because that design pattern is horrific if you multithread it.
