# 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.

## API and User Documentation
The main contribution of this project is the [`uefi` crate](./uefi/README.md).
Please refer to [docs.rs](https://docs.rs/uefi) for comprehensive documentation
of the **latest stable release**. The latest not necessarily yet published
documentation can be found in [`src/lib.rs`](./uefi/src/lib.rs), which can also
be locally viewed by running `$ cargo xtask doc --open`.
## Developer Guide
### Repository Structure
This repository provides various crates:
- [`uefi`](/uefi/README.md): High-level wrapper around various low-level UEFI
APIs. This crate makes it easy to develop Rust software that leverages safe,
convenient, and performant abstractions for UEFI functionality.
This is the **main contribution** of this project.
- [`uefi-raw`](/uefi-raw/README.md): Raw ABI-compatible types that closely
match the definitions in the UEFI Specification. They are suitable for
implementing UEFI firmware or creating interfaces to it.
- [`uefi-macros`](/uefi-macros/README.md): Helper macros used by `uefi`.
- [`uefi-test-runner`](/uefi-test-runner/README.md): A UEFI application that
runs our integration tests.
- [`uefi-std-example`](/uefi-std-example/README.md): Example UEFI app but as
Rust standard binary.
### Building and testing uefi-rs
Use the `cargo xtask` command to build and test the crate.
Available commands:
- `build`: build all the UEFI packages
- `--release`: build in release mode
- `--target {x86_64,ia32,aarch64}`: choose target UEFI arch
- `clippy`: run clippy on all the packages
- `--target {x86_64,ia32,aarch64}`: choose target UEFI arch
- `--warnings-as-errors`: treat warnings as errors
- `doc`: build the docs for the UEFI packages
- `--open`: open the docs in a browser
- `--warnings-as-errors`: treat warnings as errors
- `run`: build `uefi-test-runner` and run it in QEMU
- `--ci`: disable some tests that don't work in the CI
- `--disable-kvm`: disable hardware accelerated virtualization support in
QEMU.
Especially useful if you want to run the tests under
[WSL](https://docs.microsoft.com/en-us/windows/wsl) on Windows.
- `--example `: run an example instead of the main binary.
- `--headless`: run QEMU without a GUI
- `--ovmf-code `: path of an OVMF code file
- `--ovmf-vars `: path of an OVMF vars file
- `--release`: build in release mode
- `--target {x86_64,ia32,aarch64}`: choose target UEFI arch
- `test`: run unit tests and doctests on the host
The `uefi-test-runner` directory contains a sample UEFI app which exercises
most of the library's functionality.
Check out the testing project's [`README.md`](uefi-test-runner/README.md) for
prerequisites for running the tests.
