def <=>( other )
  case other

  else raise ArgumentError, 'expecting a Logger instance' end
end

#level=(level) ⇒ Object

call-seq:

level = :all

Set the level for the root logger. The functionality of this method is the same as Logger#level=, but setting the level to nil for the root logger is not allowed. The level is silently set to :all.
