[UEFI] is the successor to the BIOS. It provides an early boot environment for OS loaders, hypervisors and other low-level applications.
The uefi crate makes it easy to:
- Write UEFI applications in Rust (for i686, x86_64, or aarch64)
- Call UEFI functions from an OS (usually built with a custom target)
The objective is to provide safe and performant wrappers for UEFI interfaces, and allow developers to write idiomatic Rust code.
Check out the [UEFI application template] for a quick start.
This crate's features are described in [src/lib.rs].
See also the [uefi-services] crate, which provides a panic handler and
initializes the global_allocator and logger features.
The [uefi-rs book] contains a tutorial, how-tos, and overviews of some important UEFI concepts.
Reference documentation can be found on docs.rs: - docs.rs/uefi - docs.rs/uefi-macros - docs.rs/uefi-services
For additional information, refer to the UEFI specification.
For instructions on how to create your own UEFI apps, see the [tutorial].
The uefi-rs crates currently require some [unstable features]. The nightly MSRV is currently 2022-08-25.
