So one issue I can imagine being the culprit with rust is the specializing / c++ style semantics of rust generics. C code generics tend to be void* flavored or point to a struct of function pointers. Which will generate less code. Not sure how this translates to the kernel setting thoughb

That is true. Rust makes it easy to overuse monomorphisation. There are tools like `cargo-bloat` that find these.

However, most complaints are about size of “Hello World”, which in Rust is due to libstd always having debug info (to be fixed soon), and panic handling code that includes backtrace printing (because print to stdout can fail).

Printing of backtrace is very bloaty, because it parses and decompresses debug info.
