Rust Programming Language

The Rust Official Documentation describes Rust as: “A language empowering everyone to build reliable and efficient software.”

Main Features

Performance

Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages.

Reliability

Rust’s rich type system and ownership model guarantee memory-safety and thread-safety — enabling you to eliminate many classes of bugs at compile-time.

Productivity

Rust has great documentation, a friendly compiler with useful error messages, and top-notch tooling — an integrated package manager and build tool, smart multi-editor support with auto-completion and type inspections, an auto-formatter, and more.

Risks of its adoption

Relatively young language: Rapid adoption across the industry.
Currently no official support for the language by any large company: Although changing and lots of companies are already invested on it.
Buy in into single ecosystem: Necessary independent of language.

Why Rust?

Low level.
Cross-platform.
Including wasm.
Fast.
Ecosystem: crates.io.
Tooling: cargo.
Foundation: LLVM.
High assurance software: (hacspec, crucible, sealed Rust, rustbelt, etc).
Community.

Companies using it

Tooling

Crates.io: Large package ecosystem.
Cargo: Build tool support.
LLVM Backend: All LLVM tools work on Rust.

Integration

Foreign Function Interface (FFI):
- Easily usable in other languages.
- Can easily use other C-like languages.
WebAssembly (WASM):
- Native WASM support through compiler.
- It’s just another target platform.

Knowledge Base

This section includes deeper knowledge about Rust specific functionalities.

Rust toolchain

A toolchain is a specific version of the collection of programs needed to compile a Rust application. It includes, but is not limited to:

The compiler, rustc.
The dependency manager and build tool, cargo.
The documentation generator, rustdoc.
The static and/or dynamic libraries comprising the standard library for the default platform.

There are additional components that can be installed, such as:

Documentation
- The Rust Programming Language.
- The standard library.
- Various books and references.
The static and/or dynamic libraries comprising the standard library for additional platforms to cross-compile to.
The source code for the standard library.
Extra utilities:
- Code formatting via rustfmt.
- Extra lints via clippy.
- Undefined behavior checking via miri.
- Advanced editor support via rust-analyzer or the Rust Language Server.

Rustup provides ways to install, remove, update, select and otherwise manage these toolchains and their associated pieces.
