## What's Rust? Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. ## Concurrency? Rust? Libraries Futures ## What's concurrency ## What's Rust? Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. ## What's safety? ![Image](/uploads/documents/2/5/1/a/251a4 mutation • Ownership prevents double-free • Borrowing prevents use-after-free • Overall, no segfaults! ## Data races Aliasing! • A data race happens when there are two concurrent memory accesses to
