Casper-compatible NFT interface

Required Methods§

Source

fn name(&self) -> String

Returns a name of the NFT token/collection.

Source

fn symbol(&self) -> String

Returns a short symbol or abbreviation for the NFT token/collection.

Source

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

Returns the number of NFTs owned by a given account or contract

§Arguments

owner - The account to query.

§Returns

The number of NFTs owned by the account.

Source

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

Returns the owner of a specific NFT.

§Arguments

token_id - The ID of the NFT.

§Returns

The owner if it exists, else None.

Source

fn safe_transfer_from( &mut self, from: Address, to: Address, token_id: U256, data: Option<Bytes>, )

Performs a recipient check and transfers the ownership of an NFT.

Reverts unless the contract caller is the current owner, an authorized operator, or the approved spender for this NFT. Reverts if from is not the current owner, or if token_id does not reference a valid NFT. Once ownership is updated and a Transfer event is emitted, the function checks whether to is a contract hash. If it is, the contract MUST call on_cep95_received on to and revert the entire transfer if that call is absent or returns any value other than true.
