[OxidizeConf2024] C++ Migration Strategies
Bridging Legacy and Modern Systems
The push for memory-safe software has highlighted the limitations of C++ in today’s data-driven landscape, prompting organizations to explore Rust as a modern alternative. At OxidizeConf2024, Til Adam from KDAB and Florian Gilcher from Ferrous Systems presented a strategic approach to migrating from C++ to Rust, emphasizing an “Aloha” philosophy of compassion and pragmatism. With decades of experience in C++ development, Til and Florian offered insights into integrating Rust into existing codebases without requiring a full rewrite, ensuring efficiency and safety.
Drawing an analogy to music, Til compared C++ to a complex electric guitar and Rust to a simpler, joy-inducing ukulele. While C++ remains prevalent in legacy systems, its complexity can lead to errors, particularly in concurrency and memory management. Rust’s memory safety and modern features address these issues, but Florian stressed that migration must be practical, leveraging the C Application Binary Interface (C ABI) as a lingua franca for interoperability. This allows Rust and C++ to coexist, enabling incremental adoption in existing projects.
Practical Migration Techniques
The speakers outlined a multi-level migration strategy, starting with low-level integration using the C ABI. This involves wrapping C++ code in extern C functions to interface with Rust, a process Florian described as effective but limited by platform-specific complexities. Tools like cxx and autocxx simplify this by automating bindings, though challenges remain with templates and generics. Til shared examples from KDAB’s projects, where Rust was integrated into C++ codebases for specific components, reducing security risks without disrupting existing functionality.
At a higher level, Florian advocated for a component-based approach, where Rust modules replace C++ components in areas like concurrency or security-critical code. This strategy maximizes Rust’s benefits, such as its borrow checker, while preserving investments in C++ code. The speakers emphasized identifying high-value areas—such as modules prone to concurrency issues—where Rust’s safety guarantees provide immediate benefits, aligning with organizational goals like regulatory compliance and developer productivity.
Balancing Innovation and Pragmatism
Migration decisions are driven by a balance of enthusiasm, regulatory pressure, and resource constraints. Til noted that younger developers often champion Rust for its modern features, while executives respond to mandates like the NSA’s push for memory-safe languages. However, budget and time limitations necessitate a pragmatic approach, focusing on areas where Rust delivers significant value. Florian highlighted successful migrations at KDAB and Ferrous Systems, where Rust was adopted for new features or rewrites of problematic components, improving safety and maintainability.
The speakers also addressed challenges, such as the lack of direct support for C++ templates in Rust. While tools like autocxx show promise, ongoing community efforts are needed to enhance interoperability. By sharing best practices and real-world examples, Til and Florian underscored Rust’s potential to modernize legacy systems, fostering a collaborative approach to innovation that respects existing investments while embracing future-ready technologies.

[OxidizeConf2024] Continuous Compliance with Rust in Automotive Software
Introduction to Automotive Compliance
The automotive industry, with its intricate blend of mechanical and electronic systems, demands rigorous standards to ensure safety and reliability. Vignesh Radhakrishnan from Thoughtworks delivered an insightful presentation at OxidizeConf2024, exploring the concept of continuous compliance in automotive software development using Rust. He elucidated how the shift from mechanical to software-driven vehicles has amplified the need for robust compliance processes, particularly in adhering to standards like ISO 26262 and Automotive SPICE (ASPICE). These standards are pivotal in ensuring that automotive software meets stringent safety and quality requirements, safeguarding drivers and passengers alike.
Vignesh highlighted the transformation in the automotive landscape, where modern vehicles integrate complex software for features like adaptive headlights and reverse assist cameras. Unlike mechanical components with predictable failure patterns, software introduces variability that necessitates standardized compliance to maintain quality. The presentation underscored the challenges of traditional compliance methods, which are often manual, disconnected from development workflows, and conducted at the end of the development cycle, leading to inefficiencies and delayed feedback.
Continuous Compliance: A Paradigm Shift
Continuous compliance represents a transformative approach to integrating safety and quality assessments into the software development lifecycle. Vignesh emphasized that this practice involves embedding compliance checks within the development pipeline, allowing for immediate feedback on non-compliance issues. By maintaining documentation close to the code, such as requirements and test cases, developers can ensure traceability and accountability. This method not only streamlines the audit process but also reduces the mean-time-to-recovery when issues arise, enhancing overall efficiency.
The use of open-source tools like Sphinx, a Python documentation generator, was a focal point of Vignesh’s talk. Sphinx facilitates bidirectional traceability by linking requirements to code components, enabling automated generation of audit-ready documentation in HTML and PDF formats. Vignesh demonstrated a proof-of-concept telemetry project, showcasing how Rust’s cohesive toolchain, including Cargo and Clippy, integrates seamlessly with these tools to produce compliant software artifacts. This approach minimizes manual effort and ensures that compliance is maintained iteratively with every code commit.
Rust’s Role in Simplifying Compliance
Rust’s inherent features make it an ideal choice for automotive software development, particularly in achieving continuous compliance. Vignesh highlighted Rust’s robust toolchain, which includes tools like Cargo for building, testing, and formatting code. Unlike C or C++, where developers rely on disparate tools from multiple vendors, Rust offers a unified, developer-friendly environment. This cohesiveness simplifies the integration of compliance processes into continuous integration (CI) pipelines, as demonstrated in Vignesh’s example using CircleCI to automate compliance checks.
Moreover, Rust’s emphasis on safety and ownership models reduces common programming errors, aligning well with the stringent requirements of automotive standards. By leveraging Rust’s capabilities, developers can produce cleaner, more maintainable code that inherently supports compliance efforts. Vignesh’s example of generating traceability matrices and architectural diagrams using open-source tools like PlantUML further illustrated how Rust can enhance the compliance process, making it more accessible and cost-effective.
Practical Implementation and Benefits
In his demonstration, Vignesh showcased a practical implementation of continuous compliance using a telemetry project that streams data to AWS. By integrating Sphinx with Rust code, he illustrated how requirements, test cases, and architectural designs could be documented and linked automatically. This setup allows for real-time compliance assessments, ensuring that software remains audit-ready at all times. The use of open-source plugins and tools provides flexibility, enabling adaptation to various input sources like Jira, further streamlining the process.
The benefits of this approach are manifold. Continuous compliance fosters greater accountability within development teams, as non-compliance issues are identified early. It also enhances flexibility by allowing integration with existing project tools, reducing dependency on proprietary solutions. Vignesh cited the Ferrocene compiler as a real-world example, where similar open-source tools have been used to generate compliance artifacts, demonstrating the feasibility of this approach in large-scale projects.
