Rust – systems programming language

Rust is an open source, curly-brace, block-structured expression, general purpose, multi-paradigm, compiled language. It visually resembles the C language family, but differs significantly in syntactic and semantic details.

Its design is oriented toward concerns of “programming in the large”, that is, of creating and maintaining boundaries – both abstract and operational – that preserve large-system integrity, availability and concurrency.

Rust supports a mixture of imperative procedural, concurrent actor, object-oriented and pure functional styles. Rust also supports generic programming and metaprogramming, in both static and dynamic styles.

Features include:

  • Type – system static, nominal, linear, algebraic, locally inferred.
  • Multi-paradigm: pure-functional, concurrent-actor, imperative-procedural, OO:
    • First-class functions, cheap non-escaping closures.
    • Algebraic data types (called enums) with pattern matching.
    • Method implementations on any type.
    • Traits, which share aspects of type classes and interfaces.
  • Memory safety – no null or dangling pointers, no buffer overflows, no use-before-initialize or use-after-move.
  • Concurrency – lightweight tasks with message passing, no shared memory.
  • Generics – type parameterization with type classes.
  • Exception handling – unrecoverable unwinding with task isolation: task failure / unwinding, trapping, RAII / dtors.
  • Memory model – optional task-local GC, safe pointer types with region analysis.
  • Compilation model – ahead-of-time, C/C++ compatible.
  • Lightweight tasks (coroutines) with expanding stacks.
  • Fast asynchronous, copyless message passing.
  • Optional garbage collected pointers.
  • All types may be explicitly allocated on the stack or interior to other types.
  • Static, native compilation using LLVM.
  • Direct and simple interface to C code.
  • Works with existing native toolchains, GDB, Valgrind, Instruments, etc.
  • Multi-platform.
