Webb30 nov. 2024 · Rust prevents out-of-bounds memory accesses and buffer overruns via runtime bounds checks - what’s the cost of those bounds checks for a real-world, production application? Recently, a pair of critical vulnerabilities were reported in the OpenSSL project. WebbSo, in general, Rust must enforce two things: Spatial memory safety: may require bounds-check at run-time. Temporal memory safety: may require borrow-check or liveness-check at run-time. Whenever practical, it is best for the developer to use methods which do NOT require any run-time check.
