Starlette (and **FastAPI**) are based on <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, which makes it compatible with both Python's standard library <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> and <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.

# Testando

		if ref.PrimaryKey != nil && (rel.JoinTable == nil || ref.OwnPrimaryKey) {
			constraint.ForeignKeys = append(constraint.ForeignKeys, ref.ForeignKey)
			constraint.References = append(constraint.References, ref.PrimaryKey)

			if ref.OwnPrimaryKey {
				constraint.Schema = ref.ForeignKey.Schema
				constraint.ReferenceSchema = rel.Schema
