Struct polkadot_runtime_common::auctions::pallet::Pallet[−][src]

pub struct Pallet<T>(_);
Expand description

The pallet implementing the on-chain logic.

Implementations

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.

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.

Cancel an in-progress auction.

Can only be called by Root origin.

Number of auctions started so far.

Information relating to the current auction, if there is one.

The first item in the tuple is the lease period index that the first of the four contiguous lease periods on auction is for. The second is the block number when the auction will “begin to end”, i.e. the first block of the Ending Period of the auction.

Amounts currently reserved in the accounts of the bidders currently winning (sub-)ranges.

The winning bids for each of the 10 ranges at each sample in the final Ending Period of the current auction. The map’s key is the 0-based index into the Sample Size. The first sample of the ending period is 0; the last is Sample Size - 1.

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.

Trait Implementations

The block is being finalized. Implement to have something happen.

This will be run when the block is being finalized (before on_finalize). Implement to have something happen using the remaining weight. Will not fire if the remaining weight is 0. Return the weight used, the hook will subtract it from current weight used and pass the result to the next on_idle hook if it exists. Read more

The block is being finalized. Implement to have something happen. Read more

Something that should happen at genesis.

The block is being finalized. Implement to have something happen in case there is leftover weight. Check the passed remaining_weight to make sure it is high enough to allow for your pallet’s extra computation. Read more
