Primitives behind PythonNative's async rendering model: the [Suspend][pythonnative.suspense.Suspend] signal, the standard asyncio tasks that run async def component bodies, cached async values ([Resource][pythonnative.Resource] / [start_resource][pythonnative.start_resource]), and code splitting with [lazy][pythonnative.lazy].

The user-facing pieces are the [Suspense][pythonnative.Suspense] boundary component (documented with the other components) and the [use_resource][pythonnative.use_resource] hook (documented with the other hooks); this page covers the underlying machinery.
