Problem description

I write a lot of both go and rust. I'm trying to reduce context-switch friction. Is there a simple way for the rust plugin to convert v := into let v =?

Maybe a live template? postfix templates don't seem to work for since there is no dot/period

Steps to reproduce

1. open a rust file
2. make a function
3. in the function try to declare a variable (incorrectly) using go syntax (v :=)
4. wish that the awesome rust plugin would auto convert to let v =

Hi! I'm sorry, but I don't think there is such a way.

Sure, I imagine there's not way to do it today.

I'm asking how would it work? What would have to change?

This plugin already does some code rewriting (maybe ast rewriting) (example)

Hmm, I'd suggest to do it using RsElementBaseIntentionAction, like AddElseIntention. See these blog posts (1, 2) (thank to @Kobzol!). But since v := can't be parsed as a valid Rust syntax, I wouldn't expect it to be very easy 😅
