An iterator where increments and decrements are null operations.

Can be used to copy to or from a fixed address such as a register.

template <typename TIterator>

etl::fixed_iterator();

template <typename TIterator>

etl::fixed_iterator(TIterator it);

// Read 20 characters from the port.

std::copy_n(uart_read, 20, std::back_inserter<char>(buffer));

// Write the buffer of characters to the port.
