 I don't understand, you want to say the difference between
 Module::const_defined? and Module::constants

svg% ri const_defined?
-------------------------------------------------- Module#const_defined?
     mod.const_defined?( aSymbol ) -> true or false
------------------------------------------------------------------------
     Returns true if a constant with the given name is defined by mod.
        Math.const_defined? "PI"   #=> true

svg%

svg% ri Module::constants
------------------------------------------------------ Module::constants
     Module.constants -> anArray
------------------------------------------------------------------------
     Returns an array of the names of all constants defined in the
     system. This list includes the names of all modules and classes.
        p Module.constants.sort[1..5]
     produces:
        ["ARGV", "ArgumentError", "Array", "Bignum", "Binding"]
