I personally love working on projects that run full-stack locally: I find the dev feedback loop is the best. I also like to be able to just `docker-compose up` my entire project, so I tend to develop with the services inside containers.

My issue with using rust for my backend right now is that the compiles in the container are so slow. They take around 1 minute for the basic actix-web project (when just compiling the project, none of the dependencies), which completely kills the feedback loop I'm looking for. I do the same exact thing with Golang and it works much, much faster: the compiles are almost unnoticeable.

Is what I'm asking for impossible? When I just compile outside the container it takes not even 2 seconds.

[Here's the dockerfile in question](https://gist.github.com/d320d0bcbfe91f90c1d13364dc75daf8) (I'm on an M1 Mac, so I thought maybe using an arm container could help to skip translation)

[and here's the Actix web project](https://gist.github.com/92fa49a008f58c2f6cac897fa75b93a2) (although it's just the default starter project)

To be perfectly clear: I am *not* rebuilding the container from scratch over and over. I am *compiling* the project inside the container. As in:

``` Compiling fns v0.1.0 (/src) Finished dev [unoptimized + debuginfo] target(s) in 1m 28s Running `target/debug/fns` ```

the vast majority of the advice on the reddit post about my article was how to speed up the container builds. The container builds are not that big of a deal to me! I thought I was clear about this, but since so many people thought that was what I was talking about, it was clearly a communication error on my part. Sorry about that.

I am NOT talking about the first compile. When I make a change to the code, Cargo watch triggers and recompiles. I am talking about the 1 + nth compile!

TIA!
