I code Rust just fine without any fancy IDE you should give it a shot. The languages I find hardest to code without fancy IDE features are C and C++ due to their implicit casts. Rust is typically easy to code without IDE features due to its strong type system, lifetimes and few implicit casts. |

> few implicit casts
Just because it doesn't (often) implicitly convert/pun raw types doesn't mean it has "few implicit casts". Rust has large amounts implicit conversion behavior (e.g. deref coercion, implicit into), and semi-implicit behavior (e.g. even regular explicit ".into()" distances conversion behavior and the target type in code). The affordances offered by these features are significant--I like using them in many cases--but it's not exactly turning over a new leaf re: explicitness.
Without good editor support for e.g. figuring out which "into" implementation is being called by a "return x.into()" statement, working in large and unfamiliar Rust codebases can be just as much of a chore as rawdogging C++ in no-plugins vim.
Like so many Rust features, it's not breaking with specific semantics available in prior languages in its niche (C++); rather, it's providing the same or similar semantics in a much more consciously designed and user focused way.
> lifetimes
How do lifetimes help (or interact with) IDE-less coding friendliness? These seem orthogonal to me.
Lastly, I think Rust macros are the best pro-IDE argument here. Compared to C/C++, the lower effort required (and higher quality of tooling available) to quickly expand or parse Rust macros means that IDE support for macro-heavy code tends to be much better, and much better out of the box without editor customization, in Rust. That's not an endorsement of macro-everything-all-the-time, just an observation re: IDE support.
