Time based Unique IDentifiers
TUIDs are values compatible with UUIDs
They share the same base formati, so can be used instead of them. The main property of TUIDs is that they are prefixed by the time they were generated. Which allow them to be sorted and behave better on database indexes.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install tuid
# Generate a random TUID tuid = . #=> #<TUID 56342da3-7cc0-280d-f0b8-507634551518(2015-10-30 23:55:31 -0300)> # Get its generation time tuid.time #=> 2015-10-30 23:55:31 -0300 # Turn it into a String tuid.to_s #=> "56342da3-7cc0-280d-f0b8-507634551518" # Generate a TUID from a UUID formated string tuid2 = .("56342da3-7cc0-280d-f0b8-507634551518") #=> #<TUID 56342da3-7cc0-280d-f0b8-507634551518(2015-10-30 23:55:31 -0300)> # And they can be compared tuid == tuid2 #=> true
