range abstract method
Returns a subseries with positions from start
(inclusive) to end
(exclusive).
If end
is not provided, then all positions from start
to end are
returned.
A returned series may point to the same position data as this (however implementations are allowed to make a copy of positions in the range).
Valid queries are such that 0 ≤ start ≤ end ≤ positionCount.
Implementation
PositionSeries range(int start, [int? end]);
