module BSON
# A class representing the BSON MaxKey type. MaxKey will always compare greater than
# all other BSON types and values.

# @example Sorting (assume @numbers is a collection):
#
# >> @numbers.save({"n" => Mongo::MaxKey.new})
# >> @numbers.save({"n" => 0})
# >> @numbers.save({"n" => 5_000_000})
# >> @numbers.find.sort("n").to_a
# => [{"_id"=>4b5a050c238d3bace2000004, "n"=>0},

# A class representing the BSON MinKey type. MinKey will always compare less than
# all other BSON types and values.

# @example Sorting (assume @numbers is a collection):

# >> @numbers.save({"n" => -1_000_000})
# >> @numbers.save({"n" => 1_000_000})
