A standard Docker container with a NodeJS/PHP/Python app is usually around 200-300 MB (yes really), the OpenJDK JVM is around a hundred MB, but a fully statically compiled rust binary that doesn’t even depend on libc is just a couple MB and can be deployed as a tiny distroless Docker container.
It’s a lot heavier than your 8kb C++ executable but it’s nothing compared to what is required to deploy anything else.
To me, it is mostly a real blocker for using it in some embedded Linux devices due to size constraints, otherwise I personally would be using it extensively.
I’m having a hard time imagining this Goldilocks embedded device that is simultaneously big enough to run Linux (so not an actual microcontroller), yet too small for a few megabytes worth of statically-linked libraries. Got an example?
This is precisely the problem that deploy-rs solves!
why is everything in rust now
It’s easy to write, easy to build, produces lightweight and fast executables, and the type system is great. Why not rust?
Rust does not have an ABI. Everything is linked into the executables. I would not call them lightweight.

Oh, so it’s inconvenient for GPL-circumventers, too? That just sounds better and better.
