lottery

buyTicket(call: Call)

• interface: lottery.buyTicket

• summary: Buy a ticket to enter the lottery.

  This extrinsic acts as a passthrough function for call. In all situations where call alone would succeed, this extrinsic should succeed.

  If call is successful, then we will attempt to purchase a ticket, which may fail silently. To detect success of a ticket purchase, you should listen for the TicketBought event.

  This extrinsic must be called by a signed origin.

setCalls(calls: Vec<Call>)

• interface: lottery.setCalls

• summary: Set calls in storage which can be used to purchase a lottery ticket.

  This function only matters if you use the ValidateCall implementation provided by this pallet, which uses storage to determine the valid calls.

  This extrinsic must be called by the Manager origin.

startLottery(price: u128, length: u32, delay: u32, repeat: bool)

• interface: lottery.startLottery

• summary: Start a lottery using the provided configuration.

  This extrinsic must be called by the ManagerOrigin.

  Parameters:

  • price: The cost of a single ticket.

  • length: How long the lottery should run for starting at the current block.

  • delay: How long after the lottery end we should wait before picking a winner.

  • repeat: If the lottery should repeat when completed.

stopRepeat()

• interface: lottery.stopRepeat

• summary: If a lottery is repeating, you can use this to stop the repeat. The lottery will continue to run to completion.

  This extrinsic must be called by the ManagerOrigin.
