Microsoft has also developed Oxidizer, a set of crates to build scalable services in Rust, and rustc_codegen_utc, a custom Rust compiler code-generation backend that integrates Rust with the Microsoft Visual C++ internal toolchain for Windows. This move comes as Microsoft seeks to address the high number of memory-related vulnerabilities in Windows, with Azure CTO Mark Russinovich stating that Rust starts with a stronger foundation compared to C and C++ in terms of security.",
