## What it is
rbpf is a Rust crate providing a user-space virtual machine for executing eBPF programs. It includes an interpreter, an x86_64 JIT compiler, and a disassembler for eBPF bytecode.

## Use cases
- run eBPF programs in user-space applications
- embed an eBPF interpreter in a Rust project
- JIT-compile eBPF bytecode for faster execution on x86_64
- disassemble eBPF programs for inspection and debugging
- test eBPF program logic without loading it into the kernel
- build packet filtering tools based on BPF

## When to choose
- you need to execute eBPF programs outside the Linux kernel
- you want a pure-Rust, cross-platform eBPF VM for Linux, macOS, or Windows
- you are building tooling that emulates or analyzes eBPF bytecode

## When to avoid
- you need to run eBPF programs in the Linux kernel with kernel helpers and maps
- you require JIT compilation on Windows, which is not supported
- you need a production-grade verifier comparable to the kernel's

## Facets
- artifact type: library
- maturity: active
- function: interpreter, compiler, simulation
- domain: networking, developer-tools, security
- platform: windows, rust
- tags: ebpf, jit-compiler, virtual-machine, packet-filtering, disassembler, user-space, virtualization, linux, macos
