PROFILE
Arjan Seijs
Arjan Seijs developed foundational Rust support for the facebook/infer static analysis tool, focusing on memory-error detection in unsafe Rust code. He initially integrated Rust’s MIR into Infer’s analysis pipeline, enabling detection of memory issues and expanding the tool’s language coverage. In a subsequent phase, Arjan replaced the custom Rust analysis library with Charon, leveraging its JSON intermediate representation to streamline Rust code analysis. This transition involved updating build systems, test scaffolding, and CI configurations using OCaml, Rust, and Makefile. His work established a maintainable, IR-based analysis path for Rust, deepening Infer’s static analysis capabilities without introducing new bugs.

Oct 1, 20252025-10 monthly summary for facebook/infer: Delivered Rust code analysis via Charon IR translation by integrating the Charon library, replacing the previous custom Rust analysis library. Updated build configurations and test scaffolding to support Charon's JSON intermediate representation, enabling Infer to analyze Rust code through Charon's IR pipeline. This work strengthens Rust support, reduces maintenance of bespoke tooling, and sets the foundation for broader IR-based analysis.
