Rentable NFT (EIP4907)

ERC721 :

IERC721 :
Required interface of an ERC721 compliant contract.
Approval(address,address,uint256) :
Emitted when `owner` enables `approved` to manage the `tokenId` token.
ApprovalForAll(address,address,bool) :
Emitted when `owner` enables or disables (`approved`) `operator` to manage all of its assets.
Transfer(address,address,uint256) :
Emitted when `tokenId` token is transferred from `from` to `to`.
approve(address,uint256) :
Gives permission to `to` to transfer `tokenId` token to another account. The approval is cleared when the token is transferred. Only a single account can be approved at a time, so approving the zero address clears previous approvals. Requirements: - The caller must own the token or be an approved operator. - `tokenId` must exist. Emits an {Approval} event.
balanceOf(address) :
Returns the number of tokens in ``owner``'s account.
getApproved(uint256) :
Returns the account approved for `tokenId` token. Requirements: - `tokenId` must exist.
isApprovedForAll(address,address) :
Returns if the `operator` is allowed to manage all of the assets of `owner`. See {setApprovalForAll}
ownerOf(uint256) :
Returns the owner of the `tokenId` token. Requirements: - `tokenId` must exist.
safeTransferFrom(address,address,uint256) :
Safely transfers `tokenId` token from `from` to `to`, checking first that contract recipients are aware of the ERC721 protocol to prevent tokens from being forever locked. Requirements: - `from` cannot be the zero address. - `to` cannot be the zero address. - `tokenId` token must exist and be owned by `from`. - If the caller is not `from`, it must have been allowed to move this token by either {approve} or {setApprovalForAll}. - If `to` refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.
safeTransferFrom(address,address,uint256,bytes) :
Safely transfers `tokenId` token from `from` to `to`. Requirements: - `from` cannot be the zero address. - `to` cannot be the zero address. - `tokenId` token must exist and be owned by `from`. - If the caller is not `from`, it must be approved to move this token by either {approve} or {setApprovalForAll}. - If `to` refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.
setApprovalForAll(address,bool) :
Approve or remove `operator` as an operator for the caller. Operators can call {transferFrom} or {safeTransferFrom} for any token owned by the caller. Requirements: - The `operator` cannot be the caller. Emits an {ApprovalForAll} event.
supportsInterface(bytes4) :
Returns true if this contract implements the interface defined by `interfaceId`. See the corresponding https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section] to learn more about how these ids are created. This function call must use less than 30 000 gas.
transferFrom(address,address,uint256) :
Transfers `tokenId` token from `from` to `to`. WARNING: Usage of this method is discouraged, use {safeTransferFrom} whenever possible. Requirements: - `from` cannot be the zero address. - `to` cannot be the zero address. - `tokenId` token must be owned by `from`. - If the caller is not `from`, it must be approved to move this token by either {approve} or {setApprovalForAll}. Emits a {Transfer} event.
IERC721Receiver :
Interface for any contract that wants to support safeTransfers from ERC721 asset contracts.
onERC721Received(address,address,uint256,bytes) :
Whenever an {IERC721} `tokenId` token is transferred to this contract via {IERC721-safeTransferFrom} by `operator` from `from`, this function is called. It must return its Solidity selector to confirm the token transfer. If any other value is returned or the interface is not implemented by the recipient, the transfer will be reverted. The selector can be obtained in Solidity with `IERC721Receiver.onERC721Received.selector`.
IERC721Metadata :
See https://eips.ethereum.org/EIPS/eip-721
approve(address,uint256) :

Requirements: - `from` cannot be the zero address. - `to` cannot be the zero address. - `tokenId` token must exist and be owned by `from`. - If the caller is not `from`, it must have been allowed to move this token by either {approve} or {setApprovalForAll}. - If `to` refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.
safeTransferFrom(address,address,uint256,bytes) :
Safely transfers `tokenId` token from `from` to `to`. Requirements: - `from` cannot be the zero address. - `to` cannot be the zero address. - `tokenId` token must exist and be owned by `from`. - If the caller is not `from`, it must be approved to move this token by either {approve} or {setApprovalForAll}. - If `to` refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.

symbol() :
Returns the token collection symbol.
tokenURI(uint256) :
Returns the Uniform Resource Identifier (URI) for `tokenId` token.
transferFrom(address,address,uint256) :

Requirements: - `from` cannot be the zero address. - `to` cannot be the zero address. - `tokenId` token must be owned by `from`. - If the caller is not `from`, it must be approved to move this token by either {approve} or {setApprovalForAll}. Emits a {Transfer} event.
Address :
Collection of functions related to the address type
Context :
Provides information about the current execution context, including the sender of the transaction and its data. While these are generally available via msg.sender and msg.data, they should not be accessed in such a direct manner, since when dealing with meta-transactions the account sending and paying for execution may not be the actual sender (as far as an application is concerned). This contract is only required for intermediate, library-like contracts.
Strings :
String operations.
ERC165 :
Implementation of the {IERC165} interface. Contracts that want to implement ERC165 should inherit from this contract and override {supportsInterface} to check for the additional interface id that will be supported. For example: ```solidity function supportsInterface(bytes4 interfaceId) public view virtual override returns (bool) { return interfaceId == type(MyInterface).interfaceId || super.supportsInterface(interfaceId); } ``` Alternatively, {ERC165Storage} provides an easier to use but more expensive implementation.
supportsInterface(bytes4) :
See {IERC165-supportsInterface}.
IERC165 :
Interface of the ERC165 standard, as defined in the https://eips.ethereum.org/EIPS/eip-165[EIP]. Implementers can declare support of contract interfaces, which can then be queried by others ({ERC165Checker}). For an implementation, see {ERC165}.
supportsInterface(bytes4) :
Returns true if this contract implements the interface defined by `interfaceId`. See the corresponding https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section] to learn more about how these ids are created. This function call must use less than 30 000 gas.
