## What it is
rust-script is a command-line tool that runs Rust files and expressions as scripts without any setup or explicit compilation step. It generates and caches a Cargo build behind the scenes and supports declaring crate dependencies embedded within the script itself.

## Use cases
- run a rust file like a python script
- write quick one-off rust scripts with dependencies
- use rust as a scripting language with shebang
- filter command pipelines with rust expressions
- run unit tests and benchmarks from a single rust file
- prototype rust code without creating a cargo project

## When to choose
- you want to execute small Rust programs or snippets without scaffolding a Cargo project
- you need scripts in a compiled language with inline dependency declarations
- you want fast repeated runs via cached compiled artifacts

## When to avoid
- you need fast startup for frequently changing scripts since each change triggers recompilation
- you are building a full application or library where a normal Cargo project is more appropriate
- you cannot install Rust 1.74 or newer

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, build-tool, developer-tools
- domain: developer-tools, programming-languages
- platform: windows, cli, cross-platform
- tags: rust, scripting, cargo, shebang, compiled-scripts, command-line, linux, macos
