get_delta(epsilon)	Return cumulative delta at the supplied epsilon.
get_epsilon(delta)	Return cumulative epsilon at the supplied delta.
get_privacy_spent([delta])	Return cumulative privacy expenditure.
load_state_dict(state)	Restore serializable accountant state.
state_dict()	Return serializable accountant state.
would_exceed(event[, max_epsilon, count])	Return whether composing an event would exceed an epsilon limit.
