# rust-osdev/uefi-rs

Rusty wrapper for the Unified Extensible Firmware Interface (UEFI). This crate makes it easy to develop Rust software that leverages safe, convenient, and performant abstractions for UEFI functionality.

## What it is
uefi-rs is a Rust crate providing safe, convenient, and performant abstractions over the Unified Extensible Firmware Interface (UEFI). It enables developers to write UEFI applications and OS bootloaders in Rust, with supporting crates for raw ABI types and macros.

## Use cases
- write a UEFI application in Rust
- develop a bootloader for a hobby OS
- interact with UEFI boot services safely
- test UEFI software in QEMU
- build firmware utilities without unsafe C code

## When to choose
- you are doing OS development and need UEFI boot support in Rust
- you want safe, idiomatic abstractions over the UEFI spec
- you target x86_64, ia32, or aarch64 UEFI firmware

## When to avoid
- you need legacy BIOS boot support
- you are writing a hosted application that runs under a full OS rather than firmware
- you need a non-Rust language

## Facets
- artifact type: library
- maturity: active
- function: sdk, developer-tools
- domain: operating-systems, embedded-systems, developer-tools
- platform: rust, cross-platform, embedded
- tags: uefi, firmware, osdev, bootloader, no-std, qemu
