Just recently I had a need for a fairly simple webapp. Whipped up the back end in Rust in, like, an hour; only had to bolt on a couple tests for the single complex bit of business logic, because I have a high degree of confidence that the compiler has me covered for everything else.
Now it sits there quietly using 4.9 MiB of physical memory and 1.5 millicores on two of my servers, primarily serving a k8s healthcheck every couple seconds.
