Congrats to the #Rustlang and #Rust-for-#Linux community: the #LinuxKernel now contains the first useful thing built using Rust[1]! 🥳 👏
It's a network driver for Asix PHYs. It's provided as an alternative to an existing driver written in C. The features are equivalent.
For more details see https://git.kernel.org/torvalds/c/d6beb085e8ff3d9547df8a5a55f15ccc7552c5d0, https://git.kernel.org/torvalds/c/cbe0e415089636170aa6eb540ca4af5dc9842a60, and https://lwn.net/Articles/949270/
[1] reminder, until now the #kernel's Rust support was not used for anything practical upstream: https://lwn.net/Articles/952029/
Building a network driver is an excellent use case for the language.
