The physics simulator in src/physics.rs is responsible for modeling the physics and layout of the building and elevator operations. The simulator will be provided with one object to handle motor control and another to handle data collection. The physics simulator module will define traits for each of those interfaces, and the motor control and data collection objects should implement each trait, respectively.
Let's start by defining some of the type declarations for the physics module. First, let's look at a key interface—the direct motor input. Until this point, we have assumed that motor input will have simple voltage control that we can represent as a positive or negative floating point integer. This definition ...
