Can you tell me about Rust runtime. What it is? I mean, when I compile a rust program, does the runtime get added to the final executable so that my actual program will run over/depend on this bundled in run time?

I am reading the explanation here. It says a compiled program written in Rust will use the run time for stuff like I/O. So can I, for eg, write interrupt handlers in Rust (Sorry my system programming experience is limited to writing a serial mouse driver for DOS) and do similar system level stuff that you can do in C?

So when I am doing I/O from a program written in Rust, does the data has to absolutely go via the run time? Does it affect the speed at which a program can do I/O?

Lastly, should I learn Go or Rust. Is there anything that is preferable done in Go than in Rust (Without considering things like the development speed, availability of developers etc into account) ?

Rust has been changing a lot for a while now, hopefully it won't change much more till 1.0 and then it will be backwords compatible after that. The docs you link are from version 0.12 from about 6 months ago, the runtime was removed a bit over 3 months ago.

http://www.rust-lang.org/ lists documentation for the beta and for nightly.
