orthonym.rules.ring_cation_hydron#
Note
Internal API. Names and behaviour may change between releases.
Where the added hydron of a ring cation can sit: the resonance structures that
rules.ions._ring_cation_hydron_site reads, from RDKit below a work count and
from the matching of the pi bonds above it (perception.charge_shift).
Moved out of rules/ions.py so that file stays within its size budget; the
names are imported back into rules.ions.
