Rust libraries are neither dynamic (compiled separately and loaded at run 
time) nor static (compiled separately and linked at build time), they are 
always compiled together with the program.

Yes, that's how it works.  For example, there are 25 versions of the 
"itoa" library (which does the opposite of the well-known "atoi" 
function), and you could have 25 different Rust programs on your computer, 
each one using on a different version of that library.  If you build these 
programs yourself, you will end up, in your local CARGO_HOME directory, 
with a copy of the source code of the 25 versions of that library: 
itoa-0.1.0, ..., itoa-1.0.6.
