Does logrotate check diskspace before rotating a logfile?

I am trying to figure out how logrotate work regarding disk space but not able to figure it out?

Scenario:

Let say I have 2GB of the log file and free disk space is also 2 GB, does logrotate first check do we have a sufficient disk space before rotating/compressing that file

In this scenario is it going to fail as it needs 2GB of space?

              OR

logrotate going to compress this file let say ~400MB as it thinks it already has sufficient space?
