Admittedly I don’t have as much experience cross compiling with Rust, but my experience has not been so smooth. You need to install each target toolchain manually with rustup, and then some tool chains require different versions of Rust (e.g. the ESP32 RISC-V toolchain requires nightly). Another time I tried cross compiling on x86 Linux targeting Linux on ARM64, and I kept getting linking errors (or it couldn’t find an acceptable linker). I certainly agree that Rust is much better than C/C++, but it’s not quite at Zig level, at least in my (limited) experience.
