Expand description

The ERC-721 interface as defined in the standard.

Required Methods§

Source

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

Returns the amount of tokens owned by owner.

Source

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

Returns the owner of the token_id token.

Reverts if token_id does not exist.

Source

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.

Emits a Transfer event.

Source

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.

Emits a Transfer event.

Source

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

Transfers a specific NFT tokenId from one account from to another to.

Source

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.

Only a single account can be approved at a time, so approving None clears the previous approval.

Source

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.

The operator cannot be the caller.

Emits a ApprovalForAll event.

Source

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

Returns the address approved for token_id token.

Reverts if token_id does not exist.

Source

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.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
