90 This is a container for discounts that are generated by L<SL::PriceSource::Base>
93 =head1 CONSTRUCTOR FIELDS
99 The discount in percent. A discount of 0 will be ignored. If passed as
100 part of C<available_prices> it will be filtered out. If returned as
101 C<best_discount> or C<discount_from_source> it will trigger a warning.
105 A unique string that can later be understood by the creating implementation.
106 Can be empty if the implementation only supports one discount for a given
111 A localized short description of the origins of this discount.
113 =item C<price_source>
115 A ref to the creating algorithm.
119 OPTIONAL. Discounts may supply a numerical priority. Higher will trump over lower, even when
120 supplying lower discounts. Defaults to 3 (as in middle of 1-5).
124 OPTIONAL. Both indicator and localized message that the discount with this spec
125 could not be reproduced and should be changed.
127 If discount is missing, you do not need to supply anything except C<source>.
131 OPTIONAL. Both indicator and localized message that the conditions for this
132 discount are no longer valid, and that the discount should be changed.
134 If discount is missing, you do not need to supply anything except C<source>.
138 OPTIONAL. Boolean indicator that this discount was not computed for performance
139 reasons. This is only valid for PriceSources flagged as C<fast>. This discount
