| <h1 id="analysis"><a class="header" href="#analysis">Analysis</a></h1> |
| <p>This part discusses the many analyses that the compiler uses to check various |
| properties of the code and to inform later stages. Typically, this is what people |
| mean when they talk about "Rust's type system". This includes the |
| representation, inference, and checking of types, the trait system, and the |
| borrow checker. These analyses do not happen as one big pass or set of |
| contiguous passes. Rather, they are spread out throughout various parts of the |
| compilation process and use different intermediate representations. For example, |
| type checking happens on the HIR, while borrow checking happens on the MIR. |
| Nonetheless, for the sake of presentation, we will discuss all of these |
| analyses in this part of the guide.</p> |
