Mozilla to Release New Version of Rust

There're a lot of updates and new features in new version of programming language
15 April 2019   231

Mozilla released new version of Rust programming language, 1.34. The language focuses on safe memory management, provides automatic memory management and provides the means to achieve high parallelism in the execution of tasks, while avoiding the use of garbage collection and runtime.

Automatic memory management in Rust saves the developer from manipulating pointers and protects against problems arising from low-level work with memory, such as accessing the memory area after it is released, dereferencing null pointers, going out of the buffer boundaries, etc. To distribute the libraries, provide the build and manage the dependencies of the project, the Cargo package manager is developed, which allows you to get the necessary libraries for the program in one click. The library contains the crates.io repository.

These are main updates:

  • Added tools to work with alternative package registries that can coexist with the crates.io public registry in the Cargo package manager.
  • The section [registries] is provided for adding external registries to .cargo/config (located in $HOME or in the package directory), and the option "registry" appeared in Cargo.toml to use an external registry in the description of each dependency.
  • Added full support for using the ? Operator in doctests tests that allow the use of sample code from the documentation as tests.

Redox OS 0.5 Released

OS uses the concept of a microkernel, where only interaction between processes and resource management is provided at the kernel leve

After a year of development, the release of the operating system Redox 0.5, developed using the Rust language and the microkernel concept, has been prepared. Project developments are distributed under the free MIT license. For testing in VirtualBox or QEMU, ready-made boot images are offered.

The Redox user environment is based on the Orbital GUI running on Wayland. Netsurf is used as a web browser. The operating system uses the concept of a microkernel, where only interaction between processes and resource management is provided at the kernel level, and all other functionality is moved to libraries that can be used by both the kernel and user applications. All drivers are executed in user space in isolated sandbox environments. For compatibility with existing applications, a special POSIX layer is provided that allows you to run many programs without porting.
