 C programming language. Greg Fitzgerald, who had previously worked with Anatoly
 at semiconductor giant Qualcomm Incorporated, encouraged him to reimplement the
 project in the Rust programming language. Greg had worked on the LLVM compiler
-infrastructure, which underlies both the C lang C/C++ compiler as well as the
