Int32Queue class

A QueueList that efficiently stores 32-bit signed integers.

For long queues, this implementation can be considerably more space- and time-efficient than a default QueueList implementation.

Integers stored in this are truncated to their low 32 bits, interpreted as a signed 32-bit two's complement integer with values in the range -2147483648 to 2147483647.
