The Rust programming language is known for its security guarantees and performance. To enhance the functionality of the Rust compiler, unstable features (RUF) are introduced. However, the removal of these features can result in compilation failures for dependent packages and widespread failures in the ecosystem. This study aims to analyze the usage and impacts of RUF in the Rust ecosystem, utilizing novel techniques to accurately extract RUF and assess its impact.
The analysis covers the entire Rust ecosystem, consisting of 590K package versions and 140M transitive dependencies. The study reveals that there are 1000 different RUF being used in the ecosystem, with up to 44% of package versions being affected by RUF and causing compilation failures for up to 12% of package versions. To address these impacts, a RUF-compilation-failure recovery tool has been designed and implemented, which is capable of recovering up to 90% of the failures.
The study begins by extracting and tracking all RUF supported by each version of the Rust compiler. Techniques are developed to overcome challenges such as the lack of official documentation and changing syntax. Abnormal RUF status transitions are also detected to analyze the stability problems of the Rust compiler.
To analyze RUF usage, techniques for extracting RUF configurations from Rust packages are proposed. Compilation data-flow interception is utilized to accurately extract RUF usage while maintaining efficiency. Semantic identification of RUF configuration is introduced to determine whether RUF is enabled based on dependency requirements. These techniques enable precise identification of RUF usage in the ecosystem.
To quantify RUF impacts, an Ecosystem Dependency Graph (EDG) is generated by resolving package dependencies. Challenges such as sampling, package-manager-specific rules, and conditional impacts are addressed to ensure accuracy and efficiency. The EDG allows for determining both direct and transitive RUF impacts in the ecosystem.
The study provides valuable insights into the usage and impacts of RUF in the Rust ecosystem. It reveals significant impacts and stability problems, which can lead to compilation failures and unstable functionalities. To mitigate these impacts, a RUF-compilation-failure recovery tool has been developed, capable of recovering up to 90% of the failures.
The researchers conducted an ecosystem-scale study using data from the official package database, crates.io. They resolved dependencies for 592,183 package versions and extracted 182,026 RUF configurations.
The study found that 47% of RUF are not stabilized in the latest version of the Rust compiler. They also discovered abnormal RUF status transitions and suggested introducing an inactive status for unproven RUF.
The usage of RUF in the Rust ecosystem was analyzed, revealing that only 38% of RUF types become stable. 23% of RUF types are unknown or removed, resulting in compilation failures for packages that enable them.
The impacts of RUF on package versions were examined, indicating that RUF can impact up to 44% of package versions through dependencies. Unknown and removed RUF can cause compilation failures, while active and incomplete RUF can affect a large number of Rust packages.
To mitigate the impacts of RUF, a tool is proposed to detect RUF dependencies in packages and recover from compilation failures caused by RUF. Mitigation techniques successfully recovered up to 90% of package versions from compilation failure.
The study suggests mitigating RUF impacts by stabilizing their implementation and using them safely. Developers should backport fixes, limit RUF usage, enable RUF only when necessary, and audit RUF usage and dependencies.
In conclusion, the study provides valuable insights into the usage and impacts of RUF in the Rust ecosystem. The proposed mitigation techniques show promising results in recovering from compilation failures caused by RUF.

The Rust programming language is gaining popularity due to its security guarantees and performance. To extend the functionality of the Rust compiler, unstable features (RUF) are introduced. However, these features are unstable and may be removed, causing compilation failures for dependent packages. Furthermore, these impacts can propagate through transitive dependencies, leading to large-scale failures in the ecosystem. Previous research has focused on Rust code safety, neglecting the usage and impacts of RUF. Therefore, this study aims to analyze the usage and impacts of RUF in the Rust ecosystem. Novel techniques are proposed to extract RUF accurately and assess its impact on the ecosystem. The entire Rust ecosystem, consisting of 590K package versions and 140M transitive dependencies, is analyzed. The study reveals that the Rust ecosystem uses 1000 different RUF, and up to 44% of package versions are affected by RUF, causing compiling failures for up to 12% of package versions. To mitigate these impacts, a RUF-compilation-failure recovery tool is designed and implemented, which can recover up to 90% of the failures. The techniques, findings, and tools presented in this study aim to stabilize the Rust compiler and enhance the security and reliability of the Rust ecosystem.
The study begins by extracting and tracking all RUF supported by each version of the Rust compiler. Challenges such as the lack of official documentation and changing syntax are addressed by developing new techniques.

Overall, this study contributes to the understanding of RUF usage and impacts in the Rust ecosystem. The techniques and findings presented can help stabilize the Rust compiler and enhance the security and reliability of the ecosystem. The open-source implementations, tools, and data sets provided in this study are valuable resources for the community to track and fix RUF problems.
The study focuses on analyzing the usage and impacts of Rust Unstable Features (RUF) in the Rust ecosystem. The researchers conducted an ecosystem-scale study using data from the official package database, crates.io. They resolved dependencies for 592,183 package versions and extracted 182,026 RUF configurations.
The study raises three research questions: RQ1: How does RUF status evolve with time? RQ2: How do packages in the Rust ecosystem use RUF? RQ3: How does RUF impact packages in the Rust ecosystem?
In their analysis, the researchers found that 47% of RUF are not stabilized in the latest version of the Rust compiler. They also discovered 15% abnormal RUF status transitions, which can be caused by abandoned development or bugs. Some RUF can interfere with the architecture of the Rust compiler, leading to unexpected behavior. The study suggests introducing an inactive status for RUF that are not proven to be vulnerable or unstable, allowing them to still work with a warning.
The researchers also analyzed the usage of RUF in the Rust ecosystem. They found that only 38% of RUF types become stable, accounting for 21% of usages. 23% of RUF types are unknown or removed, making packages that enable them unable to compile. They discovered that 90% of package versions using RUF are still using unstabilized RUF, indicating potential instability in the ecosystem.
Furthermore, the study examined the impacts of RUF on package versions in the Rust ecosystem. They resolved dependencies and collected 139,525,225 transitive dependencies. The results showed that RUF can impact up to 44% of package versions through dependencies, almost half of the ecosystem. Unknown and removed RUF can cause compilation failures for package versions, while active and incomplete RUF can affect a large number of Rust packages.
To mitigate the impacts of RUF, the researchers proposed a new tool to detect RUF dependencies in packages and recover from compilation failures caused by RUF. They analyzed the compatibility of RUF used in packages and recommended the compatible Rust compiler version. Their mitigation technique successfully recovered up to 90% of package versions from compilation failure.
The study also provides suggestions for mitigating RUF impacts. They recommend stabilizing RUF implementation and using RUF safely. Developers should backport fixes to old versions, limit RUF usage, enable RUF only when necessary, and audit RUF usage and dependencies.
The researchers acknowledge some limitations in their study, such as the removal of local configurations and underestimation of RUF impacts. They also discuss related work on dependency analysis, ecosystem analysis via dependency, and reliability research on compilers and Rust.
In conclusion, the study provides valuable insights into the usage and impacts of RUF in the Rust ecosystem. It highlights the need for stabilizing RUF and using them safely to ensure the reliability and security of Rust packages. The proposed mitigation techniques show promising results in recovering from compilation failures caused by RUF.
