strand::require

Forward a requirement to the underlying executor.

template<
    typename Property>
constraint_t< can_require< const Executor &, Property >::value &&!is_convertible< Property, execution::blocking_t::always_t >::value, strand< decay_t< require_result_t< const Executor &, Property > > > > require(
    const Property & p) const;

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

For example:

asio::strand<my_executor_type> ex1 = ...;
auto ex2 = asio::require(ex1,
    asio::execution::blocking.never);
