Requires a Block.

Just a little heads up here because it’s not obvious.

This requires a block to be passed to it.

Example Usage

say_with_time "Reverting all service rates to nil." do
  Service.update_all( :rate, nil )
end

# Output
-- Reverting all service rates to nil.
   -> 0.3451s
   -> 2233 rows

Include items affected in output

If the result returned from the block is an Integer, the output will include a message about that number of “rows” in addition to the elapsed time.

say_with_time "Some complex, custom work" do
  counter = 0
  # ... do some stuff here that increments the counter ...
  counter
end

#=> "-- Some complex, custom work"
#=> "   -> 45.3725s"
#=> "   -> 52880 rows"
