Detailed Description

template<uint64_t LinearSteps = 1, bool PreShuffle = false>
class blender::PythonProbingStrategy< LinearSteps, PreShuffle >

This is the probing strategy used by CPython (in 2020).

It is very fast when the original hash value is good. If there are collisions, more bits of the hash value are taken into account.

LinearSteps: Can be set to something larger than 1 for improved cache performance in some cases. PreShuffle: When true, the initial call to next() will be done to the constructor. This can help when the hash function has put little information into the lower bits.
