Outline Background • RustBelt Project • Rust Types Overview Rust Semantics • Type System • The own Predict • Exclusive Ownership & Mutable Borrow Examples • Rc Logics • Hoare Logic • Separation {x = 3} x += 1 {x = 4} {True} loop {} {False} Hoare Logic Logics P: x ↦ v Ownership We own “x”, and “x” points to “v”. Disjointness Given “(x ↦ v) ∗ (y ↦ w)”, we know that “x ≠ y”, i.e. P −∗ Q Magic wand Consuming resource “P”, we can reach resource “Q”. Q P what we acually own Logics (x ↦ v) ∗ (x ↦ w) ⟹ False (x ↦ v) ∧ (x ↦ w) ⟹ v = w Separation Logic (Iris) (x = 1)
