DSL for declaring generated RustQ files in rustq.exs.

A manifest is ordinary Elixir. It can require helper modules, declare generated Rust item files, or provide custom render/build functions.

use RustQ.Config

alias RustQ.Rustler

require_file "lib/my_app/codegen/schema.ex"

rust "native/my_nif/src/generated_term_helpers.rs" do
  Rustler.term_helpers()
end

rust "native/my_nif/src/generated_schema.rs" do
  MyApp.Codegen.Schema.rust_items()
end

Run mix rustq.gen to write files and mix rustq.gen --check in CI to fail when checked-in generated files are stale.
