I have one sore spot about Rust: The Rust build tools are almost unusably slow on small ARM devices like the Raspberry Pi Zero. I can compile a simple C++ program just fine on such a device, but Rust will take ages building dependencies and requires a swap file because it eats up all the physical memory. Meanwhile, in C++ land, my distribution's package manager includes prebuilt C++ libraries and headers. I tried cross compilation but that was a nightmare to set up, and got even worse when Cargo packages depended on C libraries, which then also had to be cross compiled. In the end, I was unable to get it working, and had to give up my attempt at targeting that platform with Rust.
