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>
