EntriesManager

Git Source Manager contract that handles the acquisition of Raffl entries. *This is an extract of @cygaar_dev and @vectorized.eth ERC721A contract in order to manage efficient minting of entries. Assumptions:

An owner cannot mint more than 2**64 - 1 (type(uint64).max).
The maximum entry ID cannot exceed 2**256 - 1 (type(uint256).max).*

State Variables

_BITMASK_ADDRESS_DATA_ENTRY

Mask of an entry in packed address data.

uint256 private constant _BITMASK_ADDRESS_DATA_ENTRY = (1 << 64) - 1;

_BITPOS_NUMBER_MINTED

The bit position of numberMinted in packed address data.

uint256 private constant _BITPOS_NUMBER_MINTED = 64;

_BITMASK_ADDRESS

The mask of the lower 160 bits for addresses.

uint256 private constant _BITMASK_ADDRESS = (1 << 160) - 1;

_currentIndex

The next entry ID to be minted.

uint256 private _currentIndex;

_packedOwnerships

mapping(uint256 => uint256) private _packedOwnerships;

_packedAddressData

mapping(address => uint256) private _packedAddressData;

Functions

totalEntries

Returns the total amount of entries minted in the contract.

function totalEntries() public view virtual returns (uint256 result);

balanceOf

Returns the number of entries in owner’s account.

function balanceOf(address owner) public view virtual returns (uint256);

ownerOf

*Returns the owner of the entryId. Requirements:

entryId must exist.*

function ownerOf(uint256 entryId) public view virtual returns (address);

_packedOwnershipOf

Returns the packed ownership data of entryId.

function _packedOwnershipOf(uint256 entryId) private view returns (uint256 packed);

_packOwnershipData

Packs ownership data into a single uint256.

function _packOwnershipData(address owner) private pure returns (uint256 result);

_mint

*Mints quantity entries and transfers them to to. Requirements:

to cannot be the zero address.
quantity must be greater than 0.*

function _mint(address to, uint256 quantity) internal virtual;

_revert

For more efficient reverts.

function _revert(bytes4 errorSelector) internal pure;

Errors

BalanceQueryForZeroAddress

Cannot query the balance for the zero address.

error BalanceQueryForZeroAddress();

OwnerQueryForNonexistentEntry

The entry does not exist.

error OwnerQueryForNonexistentEntry();
