◆ current

Discrete_interval* Discrete_intervals_list::current

When many intervals are provided at the beginning of the execution of a statement (in a replication slave or SET INSERT_ID), "current" points to the interval being consumed by the thread now (so "current" goes from "head" to "tail" then to NULL).

◆ elements

◆ first_interval

Discrete_interval Discrete_intervals_list::first_interval

To avoid heap allocation in the common case when there is only one interval in the list, we store the first interval here.
