## What it is
The official Rust monorepo containing the rustc compiler, standard library, and documentation for the Rust programming language. Rust is a systems language focused on performance, memory safety, and reliability through its ownership-based type system.

## Use cases
- build reliable and efficient systems software
- compile rust programs from source
- write memory-safe low-level code without a garbage collector
- develop embedded firmware in a safe language
- build fast command-line tools
- compile rust to webassembly for the browser
- contribute to the rust compiler itself

## When to choose
- you need a fast, memory-safe systems language with no garbage collector
- you want a mature toolchain with cargo, rustfmt, clippy, and rust-analyzer
- you are targeting embedded devices, network services, or WebAssembly
- you want strong compile-time guarantees against data races and memory bugs

## When to avoid
- you need rapid prototyping with quick compile times
- your team cannot invest in learning ownership and borrow checking
- you depend on an ecosystem or runtime available only in another language
- you want a simple scripting experience for small automation tasks

## Facets
- artifact type: cli-tool
- maturity: stable
- function: compiler, programming-language, type-system, package-manager, build-tool, linter, formatter, documentation
- domain: programming-languages, compilers, developer-tools, embedded-systems, web-development
- platform: windows, cross-platform, cli, wasm, embedded
- tags: rust, rustc, cargo, memory-safety, ownership-model, systems-programming, monorepo, standard-library, command-line, linux, macos
