Rust: Difference between revisions

Rust has a comparable amount of runtime to C and C++, and has set up its standard library to be amenable towards OS development. Specifically, the standard library is(std) splitconsists intoof two smaller parts: core and stdalloc. Core isconsists of the lowestprimitive, platform-levelindependent aspectscomponents only,of andthe standard library. It doesn't include things like allocation, threading, and other higher-level features. Alloc is used for managing heap allocations, smart pointers, and simple data collections. Std builds on top of core and alloc to add themother OS dependent features, such as files and processes. Using only core and alloc instead of std is as easy as adding anthe '''no_std''' annotation into your main source file.

Rust went through a long and public development process, and used to have a significantly larger runtime. There were lots of experiments pre-1.0, and sothus these projects are of historical interest, but mayaren't guaranteed to run or noteven build.
