GC.compact

# File tmp/rubies/ruby-3.0.5/gc.rb, line 212
def self.compact
  Primitive.gc_compact
end

This function compacts objects together in Ruby’s heap. It eliminates unused space (or fragmentation) in the heap by moving objects in to that unused space. This function returns a hash which contains statistics about which objects were moved. See GC.latest_gc_info for details about compaction statistics.

This method is implementation specific and not expected to be implemented in any implementation besides MRI.
