Short Paper: Rusty Types for Solid Safety

Content Provider	ACM Digital Library
Author	Benitez, Sergio
Abstract	Programs operating "close to the metal" necessarily handle memory directly. Because of this, they must be written in languages like C or C++. These languages lack any kind of guarantee on memory or race safety, often leading to security vulnerabilities and unreliable software. Ideally, we would like a practical language that gives programmers direct control over memory and aliasing while also offering race and memory safety guarantees. We present Rusty Types and an accompanying type system, inspired by the Rust language, that enable memory-safe and race-free references through ownership and restricted aliasing in the type system. In this paper, we formally describe a small subset of the syntax, semantics, and type system of Metal, our Rust-based language that enjoys Rusty Types. Our type system models references and ownership as capabilities, where bindings have indirect capabilities on value locations. We also present speculative extensions to Rusty Types that allow greater flexibility in single threaded programs while maintaining the same guarantees.
