Implementations

impl<T> Pallet<T>

where T: Config,

pub fn new_auction( origin: <T as Config>::RuntimeOrigin, duration: <<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number, lease_period_index: <<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::LeasePeriod, ) -> Result<(), DispatchError>

Create a new auction.

This can only happen when there isn’t already an auction in progress and may only be called by the root origin. Accepts the duration of this auction and the lease_period_index of the initial lease period of the four that are to be auctioned.

pub fn bid( origin: <T as Config>::RuntimeOrigin, para: Id, auction_index: u32, first_slot: <<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::LeasePeriod, last_slot: <<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::LeasePeriod, amount: <<<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::Currency as Currency<<T as Config>::AccountId>>::Balance, ) -> Result<(), DispatchError>

Make a new bid from an account (including a parachain account) for deploying a new parachain.

Multiple simultaneous bids from the same bidder are allowed only as long as all active bids overlap each other (i.e. are mutually exclusive). Bids cannot be redacted.

• sub is the sub-bidder ID, allowing for multiple competing bids to be made by (and funded by) the same account.
• auction_index is the index of the auction to bid on. Should just be the present value of AuctionCounter.
• first_slot is the first lease period index of the range to bid on. This is the absolute lease period index value, not an auction-specific offset.
• last_slot is the last lease period index of the range to bid on. This is the absolute lease period index value, not an auction-specific offset.
• amount is the amount to bid to be held as deposit for the parachain should the bid win. This amount is held throughout the range.

pub fn cancel_auction( origin: <T as Config>::RuntimeOrigin, ) -> Result<(), DispatchError>

Cancel an in-progress auction.

Can only be called by Root origin.

impl<T> Pallet<T>

where T: Config,

pub fn handle_bid( bidder: <T as Config>::AccountId, para: Id, auction_index: u32, first_slot: <<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::LeasePeriod, last_slot: <<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::LeasePeriod, amount: <<<T as Config>::Leaser as Leaser<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number>>::Currency as Currency<<T as Config>::AccountId>>::Balance, ) -> Result<(), DispatchError>

Actually place a bid in the current auction.

• bidder: The account that will be funding this bid.
• auction_index: The auction index of the bid. For this to succeed, must equal the current value of AuctionCounter.
• first_slot: The first lease period index of the range to be bid on.
• last_slot: The last lease period index of the range to be bid on (inclusive).
• amount: The total amount to be the bid for deposit over the range.
