The PrizeDistributionBuffer contract provides historical lookups of PrizeDistribution struct parameters (linked with a Draw ID) via a circular ring buffer. Historical PrizeDistribution parameters can be accessed on-chain using a draw ID to calculate ring buffer storage slots. The PrizeDistribution parameters can be created by manager/owner and existing PrizeDistribution parameters can only be updated by the owner. When adding a new PrizeDistribution basic sanity checks will be used to validate the incoming parameters.
Allows to initialize the contract during the deployment. Initialize for PrizeDistributionBuffer.
Adds new PrizeDistribution record to ring buffer storage. Only callable by the owner or manager.
Sets existing PrizeDistribution with new PrizeDistribution parameters in ring buffer storage. Retroactively updates an existing PrizeDistribution and should be thought of as a "safety" fallback. If the manager is setting invalid PrizeDistribution parameters the owner can update the invalid parameters with correct parameters.
