## What it is
Rune is an embeddable dynamic programming language for Rust, running on an efficient stack-based virtual machine. It offers clean Rust integration, async-first execution, hot reloading, and native support for macros, pattern matching, and constant evaluation.

## Use cases
- embed a scripting language in a Rust application
- run user-provided scripts safely at runtime
- hot reload game or app logic without recompiling
- write async scripts with select and generators
- evaluate configuration or plugin logic dynamically

## When to choose
- you need an embeddable scripting language with first-class Rust integration
- you want async support and hot reloading in a scripting layer
- you prefer a memory-safe dynamic language via reference counting

## When to avoid
- you need a mature language with a large ecosystem like Lua or Python
- you require maximum raw performance from compiled native code
- you need a statically typed language

## Facets
- artifact type: library
- maturity: active
- function: programming-language, interpreter, compiler
- domain: programming-languages, developer-tools
- platform: rust, cross-platform
- tags: scripting-language, embeddable, virtual-machine, hot-reloading, async, automation
