Nice, faster rust builds are always welcome.
I wonder if in the future some service might even offer prebuilt crates for the various architectures. I think that idea was brought up at some point.
In Elixir, when performance is needed and it's appropriate, we can use Rustler [0], however it's a PITA to ask developers to install rust, and you need it on CI etc to build the binaries.
A recent solution was to precompile these binaries. It's great.
