The function returns an array of all data stored in the given dictionary, every pair is represented as two consecutive element of the resulting array. Thus the dictionary of N pairs is converted into a vector of length 2N where keys are at positions 0, 2, 4, ..., 2N-1 and corresponding dependent data are at positions 1, 3, 5, ..., 2N. If keys are all scalars of same type then get_keyword function can be used to search in the resulting array.
If the destructive parameter is nonzero then the function may avoid copying of keys to the resulting array by moving them out from the dictionary. This is faster but the dictionary will become empty at the end of the operation. The destructive parameter does not have any effect if the dictionary is used as a value of more than one variable. Thus it is safe to make this parameter nonzero as soon as the variable passed to the function as dict is no longer in use after the function call and there's no need to inspect the whole program to check if other variables may be affected.
The function returns a vector of even length.
