> Rust can't count on OSes having Rust's standard library built-in, so Rust executables bundle bits of the Rust's standard library (300KB or more). Fortunately, it's a one-time overhead. No, it's not, especially if you have multiple binaries. There are hacks, like using a multi-call single binary, (forget about file-based privilege separation), or using an unmaintained fork of cargo to build a rust toolchain capable of dynamic linking libstd. See: https://users.rust-lang.org/t/link-the-rust-standard-library-dynamically/29175/4 https://users.rust-lang.org/t/link-the-rust-standard-library... and https://github.com/johnthagen/min-sized-rust https://github.com/johnthagen/min-sized-rust I'd be interested in any up-to-date trick to do better than this.
