The general purpose programming language RUST 1.71 has been released under the auspices of the independent non-profit organization Rust Foundation. Developed by the Mozilla project, RUST focuses on safe memory work and achieving high parallelism of tasks without the use of a garbage collector or Runtime. The language offers methods to prevent errors when manipulating signs and protects against low-level memory issues, such as accessing released memory, buffer overflows, and more. To distribute libraries and manage dependencies, RUST uses the Cargo package manager. Libraries can be hosted on the crates.io repository.[1]
RUST ensures safe memory work during compilation through reference checking, tracking object ownership, considering object lifetimes, and evaluating memory access correctness during code execution. The language also provides features to protect against integer overflow, mandatory variable initialization, improved error handling in the standard library, immutable links, default variables, and strong static typing to minimize logical errors.
The main innovations in RUST 1.71 include:
- Stabilized support for ‘Extern “C-Unwind’ ABI boundaries (‘Extern “C-Unwind) that maintains safe behavior even when an unwinding process is initiated due to program completion or C++-style exceptions that cross the ABI boundary. This ensures safe execution when exceptions arise within the same programming language but affect code in another language.[2]
- Stabilized support for debug visualizer attributes ‘#[debug_visualizer (Natvis_file = “…”)]’ and ‘#[debug_visualizer (gdb_script_file = “…”)]’ to improve debugging when inspecting data structures created by libraries. These attributes allow the use of Microsoft Natviz and gdb scripts for better visualization. Scripts are available for the standard library and can now be included for third-party libraries as well.
- On the Windows platform, RUST now allows the use of functions from dynamic libraries that were not available during assembly. This enables easier cross-compilation and reduces the need to install unnecessary libraries in the assembly environment. The attribute ‘#[Link]’ now includes the ‘kind =
