However, using #! limits the amount of software support that you can get from the larger Rust community as a majority of libraries require the standard library. Developers looking to target software for embedded platforms may forego the standard library with #! to exclusively use the no-batteries-included core library for smaller binary sizes and improved performance.
It contains only basic platform-independent types such as Option, Result, and Iterator. It is this integration with LLVM that allows Rust to obtain greater performance than equivalent C applications compiled with Clang, making Rust software designed with libcore lower level than C. It interfaces directly with LLVM primitives, which allows Rust to be platform and hardware-agnostic. The Rust Core Library is the dependency-free foundation of the Rust Standard Library. Performance of idiomatic Rust is comparable to the performance of idiomatic C++. This has led to a feature set with an emphasis on safety, control of memory layout, and concurrency. The goal of Rust is to be a good language for creating highly concurrent and highly safe systems, and programming in the large. It is designed to be a "safe, concurrent, practical language", supporting pure-functional, imperative-procedural, and object-oriented styles. Rust is a general-purpose, multi-paradigm, compiled programming language sponsored by Mozilla Research.
