##### io_context::basic_executor_type::require (7 of 8 overloads)

Obtain an executor with the specified `allocator` property.

    template<
        typename OtherAllocator>
    constexpr basic_executor_type< OtherAllocator, Bits > require(
        execution::allocator_t< OtherAllocator > a) const;

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

For example:

    auto ex1 = my_io_context.get_executor();
    auto ex2 = asio::require(ex1,
        asio::execution::allocator(my_allocator));
