Returns the contract environment associated with the module.

impl OdraContract for Erc721Token

type HostRef = Erc721TokenHostRef

The host reference type.

type ContractRef = Erc721TokenContractRef

The contract reference type.

type InitArgs = Erc721TokenInitArgs

The init args type.

type UpgradeArgs = NoArgs

The upgrade args type.

impl OwnedErc721WithMetadata for Erc721Token

fn init(&mut self, name: String, symbol: String, base_uri: String)

Initializes the module.

fn name(&self) -> String

Returns the token collection name.

fn symbol(&self) -> String

Returns the token collection symbol.

fn base_uri(&self) -> String

Returns the base URI for the token collection.

fn balance_of(&self, owner: &Address) -> U256

Returns the amount of tokens owned by owner.

fn owner_of(&self, token_id: &U256) -> Address

Returns the owner of the token_id token.

fn safe_transfer_from(&mut self, from: &Address, to: &Address, token_id: &U256)

Safely transfers token_id token from from to to, checking the recipient contract uses Erc721Receiver.

fn safe_transfer_from_with_data( &mut self, from: &Address, to: &Address, token_id: &U256, data: &Bytes, )

Safely transfers token_id token from from to to, checking the recipient contract uses Erc721Receiver, passes additional data.

fn transfer_from(&mut self, from: &Address, to: &Address, token_id: &U256)

Transfers a specific NFT tokenId from one account from to another to. Emits a Transfer event.

fn approve(&mut self, approved: &Option<Address>, token_id: &U256)

Grants permission to approved to transfer token_id token. The approval is cleared when the token is transferred.

fn set_approval_for_all(&mut self, operator: &Address, approved: bool)

Approves or removes operator for the caller. Operators can call transfer_from or safe_transfer_from for all tokens owned by the caller.

fn get_approved(&self, token_id: &U256) -> Option<Address>

Returns the address approved for token_id token.

fn is_approved_for_all(&self, owner: &Address, operator: &Address) -> bool

Returns if the operator is allowed to manage all of the tokens of owner.

fn renounce_ownership(&mut self)

If the contract’s owner chooses to renounce their ownership, the contract will no longer have an owner. This means that any functions that can only be accessed by the owner will no longer be available.

fn transfer_ownership(&mut self, new_owner: &Address)

Transfers ownership of the module to new_owner. This function can only be accessed by the current contract owner.

fn owner(&self) -> Address

Returns the address of the current owner.

fn mint(&mut self, to: &Address, token_id: &U256)

Mint a token and assigns it to to.

fn burn(&mut self, token_id: &U256)

Burns token.
