===== Rust =====

The %%FreeBSD%% Rust team takes care of [[https://www.rust-lang.org/|Rust Programming Language]] and Rust %%FreeBSD%% [[Ports]] and Packages.

  * [[https://www.freshports.org/lang/rust|lang/rust]] tracks Rust Stable and is updated every 6 weeks. It uses ''%%lang/rust-bootstrap%%'' to bootstrap.

  * [[https://www.freshports.org/lang/rust-nightly|lang/rust-nightly]] tracks Rust Nightly and is updated weekly. It uses prebuilt bootstraps provided by upstream, which are currently limited to ''%%amd64%%'' and ''%%i386%%'' architectures.
  * [[https://www.freshports.org/lang/rust-bootstrap|lang/rust-bootstrap]] creates cross-compiled bootstraps for all supported architectures which are later used to build ''%%lang/rust%%''.
  * Cargo integration is available in the ports framework via ''%%USES=cargo%%'' (Mk/Uses/cargo.mk)

===== Support =====

We currently maintain [[https://www.freshports.org/lang/rust|lang/rust]] for the following architecture and release combinations:

  * %%FreeBSD%% 11.4+ for i386, amd64, armv6
  * %%FreeBSD%% 12.1+ additionally for: armv7, aarch64 (arm64) ((< 12.1 not supported due to a bug in rtld)), powerpc64 ELFv1 ((13.0 will use the new ELFv2 ABI))
  * %%FreeBSD%% 13.0+ additionally for: powerpc64 Big Endian ELFv2, powerpc64 Little Endian ELFv2, riscv64 ((requires custom kernel with COMPAT_FREEBSD11))

===== Rust in the FreeBSD Kernel =====

Johannes Lundberg((https://github.com/johalun)) created a [[https://github.com/johalun/rustkpi/tree/master/rust/kmod-rustkpi|RustKPI FreeBSD Kernel Module]]) and [[https://github.com/johalun/rustkpi/tree/master/rust/kmod-e1000|e1000 Rust FreeBSD Network Driver example]] and [[https://github.com/johalun/rustkpi/tree/master/rust/kmod-helloworld|Hello World Example]] as part of his Masters Thesis on [[https://github.com/johalun/rustkpi/blob/master/thesis.pdf|Safe Kernel Programming with Rust (2018, PDF)]].

Anatol Ulrich((https://github.com/spookyvision)) wrote a [[https://github.com/spookyvision/hello-freebsd-rust|Hello world FreeBSD kernel module in Rust]]. (github.com, 2021)

In August 2022, David Young((https://github.com/sciguy16)) of NCCGroup posted a [[https://research.nccgroup.com/2022/08/31/writing-freebsd-kernel-modules-in-rust/|Writing FreeBSD Kernel Modules in Rust research article]] and accompanying [[https://github.com/nccgroup/freebsd-kernel-module-rust|BSD-Licensed code repository]], based on Johannes Lundberg's original work, updated to target Rust 2021.
