As a fan and user of both Rust and VS Code, it's still pretty bad. It crashes less than it used to six months ago, but the autocompletion is still near useless. It doesn't support traits as far as I can tell, for example.
I can vouch for CLion with intellij-rust, it is by far the best Rust editor/IDE available at the moment. RLS still suffers from slow/no auto completion and crashes too much for my liking. The pace and features that are coming out of the team working on intellij-rust is amazing: https://intellij-rust.github.io/thisweek/.
Rust is so exciting to me that I'll probably do this. But I absolutely HATE having to maintain multiple editors. It's like playing two pianos where the keys are all in different places. I will spend hours trying to make one like the other but it'll just never quite be right so my coding rhythm. will be discordant and janky.
I wish there was a trivial way to say to intellij, "steal all my config from vscode"
Same experience here. Was learning rust with vscode, and it would only show half of the compiler error output (e.g. the part that recommends how to fix the error wasn't shown).
In the latest vscode release they now support multiline error messages so maybe the situation will improve.
