Meta's Transition from C to Rust on Mobile
Meta is modernizing its mobile systems by transitioning from legacy C code to Rust, aiming for improved performance and safety.
Meta is undertaking a significant project to rewrite its core messaging system, which has relied on decades-old C code, by transitioning to Rust. This change is part of a broader effort to modernize their systems at scale. In a recent episode of the Meta Tech Podcast, software engineers Elaine and Buping discuss the challenges and motivations behind this transition. The move to Rust is expected to enhance performance and safety in Meta’s mobile applications.
