Rust's modules (crates) can easily be packaged and distributed once all the compilation and testing is done, regardless of whether they are libraries or executables. First, let's take a look at Rust binaries in general.

Rust libraries and binaries
There are executable binaries and libraries in Rust. When these Rust programs use dependencies, they rely on the linker to integrate those so it will work on—at least—the current platform. There are two major types of linking: static and dynamic—both of which are somewhat dependent on the operating system.
