Rust is a powerful systems programming with strong memory guarantees. Rust allows for concise expression at a high-level, while still producing fast low-level code. However, Rust does not guarantee the calling conventions and layout of structures in memory, which makes it difficult to write external applications that interface with Rust; Rust lacks a standardized ABI. Standardizing Rust's ABI has been brought up before, but has usually gone nowhere due to the difficulty of the task. In this post, we outline the benefits and stumbling-blocks of a stable ABI, as well as suggest a semi-novel technique as to how such an ABI could be implemented.
