================================================== STORAGE =================================================

Unique identifier for the storage slot where the Layout struct is stored. Derived from the ERC7201 formula. STORAGE_SLOT: TO-DO

Layout

struct Layout {
  mapping(uint256 => struct DynamicSignedPriceFacetStorage.CampaignInfo) campaignsInfo;
}

CampaignInfo

struct CampaignInfo {
  uint256 initialPrice;
  address signer;
  uint256 lastPriceUsed;
}

layout

function layout() internal pure returns (struct DynamicSignedPriceFacetStorage.Layout l)

Retrieves a reference to the Layout struct stored at a specified storage slot

setAndCheckPriceFacet

function setAndCheckPriceFacet(struct DynamicSignedPriceFacetStorage.Layout l, bytes postFractionPriceData) internal returns (uint256, uint256)

Sets the price of a fraction, in terms of input packets, for a campaign.

Parameters

Name	Type	Description
l	struct DynamicSignedPriceFacetStorage.Layout	A reference to the Layout struct in storage.
postFractionPriceData	bytes	The ABI-encoded data containing the following: - `initialPrice`: The price (in terms of input packets) required to purchase a single fraction initially. - `signer`: The party that is the signer of the price messages.

getPurchasePrice

function getPurchasePrice(struct DynamicSignedPriceFacetStorage.Layout l, uint256 campaignId, bytes extraData) internal returns (uint256)
