UnpackTuple modifications #87

Closed maierlars closed 3 years ago

maierlars commented 3 years ago

This is a small modification to the unpackTuple API. When using unpackTuple on a slice, the underlying array is expected to have exactly the length of the tuple. Otherwise the new error code BadTupleSize is thrown. For ArrayIterators the function was renamed to unpackPrefixAsTuple to indicate that it behaves differently. This function will forward the iterator and read the given number of elements and does not expect the iterator to be at the end position after everything was read. If you want to extract a prefix from a slice use ArrayIterator(slice).unpackPrefixAsTuple<...>() instead.

To allow unpacking of nested tuples, e.g. slice.unpack<int, std::tuple<int, int>, std::string>() an Extractor for tuples was added.
