The project is a Discord bot that depends on crates like <code>sysinfo</code>, <code>tikv-jemallocator</code>, and <code>sea-orm</code> (SQLite).</p> <h2 id="background">Background</h2> <p>Zig ships with a multi-platform libc and cross-compilation toolchain. <code>cargo-zigbuild</code> leverages Zig as the linker to enable Rust cross-compilation — usually much more convenient than setting up a cross toolchain yourself. That said, targeting FreeBSD comes with some unique gotchas.</p>
