Builds and loads a Rustler NIF crate generated entirely from Rusty-Elixir.

use RustQ.Native makes the current module a native compilation unit and imports RustQ.Meta. Public entrypoints use defnif; generated helper functions use defrust or defrustp.

defmodule MyApp.Native do
  use RustQ.Native

  @spec add(integer(), integer()) :: integer()
  defnif add(left, right), do: left + right
end

RustQ generates the crate under the Mix build directory, compiles it with Cargo, copies the native library into the application's priv/native directory, and injects the NIF loader. No checked-in Rust or Cargo files are required for this path.

Genuine native policy remains explicit. Use :otp_app, :crate, :mode, :cargo, or :crates only when their inferred defaults are not appropriate. Generated crates are formatted before compilation. Existing RustQ.Meta options such as :rust_sources, :rust_packages, and :callable_modules may be passed alongside them.

Existing and precompiled crates can use RustQ as an item generator without transferring build or loading ownership:

use RustQ.Native, build: false, load: false

RustQ.Native.items/1 then returns ABI-prepared functions, codecs, and resource implementations for splicing into the externally-owned crate.
