Abstract

Combining the actor-model with shared memory for performance is efficient but can introduce data-races. Existing approaches to static data-race freedom are based on uniqueness and immutability, but lack flexibility and high performance implementations. Our approach, based on deny properties, allows reading, writing and traversing unique references, introduces a new form of write uniqueness, and guarantees atomic behaviours.
