	Hash operator.

Detailed Description

Hash functor for using IntVect tiles as unordered_map keys.

Hashes all SpaceDim components (FNV-1a). Hash collisions are harmless: std::unordered_map distinguishes entries by key equality (IntVect::operator==), not by hash, so a collision only affects performance and never returns a wrong value.

[in]
