  1. > way too big https://github.com/tormol/tiny-rust-executable This produces a 137 byte binary. Obviously AMD64 isn't used in embedded, but I've seen ARM ones that are in the ~256 range. It's all in how you use it. Of course, if you don't…

  2. https://github.com/tormol/tiny-rust-executable got it to 137, but here's a blog post explaining the process to get it to 151: http://mainisusuallyafunction.blogspot.com/2015/01/151-byte-...

  3. …really a fair comparison. The smallest "hello world" binary rustc has ever produced was 137 bytes. https://github.com/tormol/tiny-rust-executable

  4. …for Rust is effectively the same as in C; the smallest binary rustc has produced is 137 bytes https://github.com/tormol/tiny-rust-executable The defaults do not focus on size reduction because we aren't in the 1970s anymore, though, it's…

  5. The smallest Rust binary ever produced was 145 bytes. https://github.com/tormol/tiny-rust-executable That is a bit extreme but it demonstrates the lower bound. There's a lot of things you can do to drop sizes, depending on the specifics of…

  6. The smallest Rust binary that does something that I've ever seen is 145 bytes https://github.com/tormol/tiny-rust-executable (I saw a wasm one get a bit lower but that isn't really apples to apples)

  7. https://github.com/tormol/tiny-rust-executable (See also http://mainisusuallyafunction.blogspot.com/2015/01/151-byte-... which was the original implementation, this shaved a few more bytes off)
