Prerequisites

1. stable rust toolchains: rustup toolchain install stable
2. nightly rust toolchains: rustup toolchain install nightly --component rust-src
3. (if cross-compiling) rustup target: rustup target add ${ARCH}-unknown-linux-musl
4. (if cross-compiling) LLVM: (e.g.) brew install llvm (on macOS)
5. (if cross-compiling) C toolchain: (e.g.) brew install filosottile/musl-cross/musl-cross (on macOS)
6. bpf-linker: cargo install bpf-linker (--no-default-features on macOS)

Build & Run

Use cargo build, cargo check, etc. as normal. Run your program with:

RUST_LOG=info cargo run --release --config 'target."cfg(all())".runner="sudo -E"'

Cargo build scripts are used to automatically build the eBPF correctly and include it in the program.
