Rust + Diesel + GitLab + CI🔗

The folks over at GitLab give away some free compute power to allow users to have CI builds of their project. It is very straightforward to get Rust projects to build within a CI environment. This post is going to take that build process one small step further, we’re going to build a Rust project that uses the Diesel ORM. This adds a step of complexity since to compile a Diesel project you need to have a postgresql database accessible if you’re using the infer_schema!() macro.

Note: diesel has instructions for using diesel print-schema instead of using infer_schema!() in version 1.3.x. It has been proposed to move away from infer_schema!(), but that issues was closed because infer_schema!() is still useful. A redditor commented that infer_schema!() has been deprecated in diesel 1.3.

Actix::From(Rocket)🔗

I was inspired by Nick’s post to migrate my code from Rocket to Actix. I have also been nagged by recent struggles with the nightly compiler and its compatibility with all the other crates that I use and other the platforms that I use; my code runs on 32/64 bit arm and 32/64 bit x86. When I started using Rocket around a year ago, the nightly compiler was just as stable as the stable compiler, but things have changed as rust is a growing eco system.

The above post stated how far actix has come regarding ergonomics and that migrating from Rocket to Actix was painless. I had a little bit of a struggle, and I think is worthwhile sharing for anyone else wishing to make this move.
