The first release of the Aya BPF library has been announced; this project
allows the writing of BPF programs in the Rust language. “Over the
last year I’ve talked with many folks interested in using eBPF in the Rust
community. My goal is to get as many of you involved in the project as
possible! Now that the rustc target has been merged, it’s time to build a
solid foundation so that we can enable developers to write great eBPF
enabled apps“.
