Everything has a runtime, except perhaps hand-rolled assembly. Rust today has a C-like runtime, which is bare minimum and makes it possible to FFI easily. For the most part you can pretend it doesn't exist; it doesn't affect programs. In the past, Rust did have a bulkier runtime with a green thread scheduler and libuv; a runtime that "mattered".
