Obtain an executor with the inline_exception_handling.propagate property.

basic_inline_executor< execution::inline_exception_handling_t::propagate_t > require(
    execution::inline_exception_handling_t::propagate_t ) const;

Do not call this function directly. It is intended for use with the require customisation point.

For example:

boost::asio::inline_executor ex1;
auto ex2 = boost::asio::require(ex1,
    boost::asio::execution::inline_exception_handling.propagate);
