Is it possible to create collision free hash function for a data structure with specific properties.

The datastructure is int[][][]
It contains no duplicates
The range of integers that are contained in it is defined. Let's say it's 0..1000, the maximal integer is definitely not greater than 10000.

Big problem is that this hash function should also be very fast. Is there a way to create such a hash function? Maybe at run time depending on the integer range?
