NEP-11 non-fungible token standard trait.

Contracts implementing this trait are compliant with the NEP-11 NFT standard on Neo N3.

Required Methods

fn symbol(&self) -> NeoResult<NeoString>

Returns the token symbol.

fn decimals(&self) -> NeoResult<u8>

Returns the number of decimals (0 for indivisible NFTs).

fn total_supply(&self) -> NeoResult<NeoInteger>

Returns the total supply of issued tokens.

fn balance_of(&self, account: &NeoByteString) -> NeoResult<NeoInteger>

Returns the token balance of the given account.

fn tokens_of(&self, account: &NeoByteString) -> NeoResult<NeoArray<NeoValue>>

Returns an iterator of token IDs owned by the account.

fn transfer( &self, to: &NeoByteString, token_id: &NeoByteString, data: &NeoValue, ) -> NeoResult<bool>

Transfers the NFT identified by token_id to to.

fn owner_of(&self, token_id: &NeoByteString) -> NeoResult<NeoByteString>

Returns the owner of the given token.

fn properties(&self, token_id: &NeoByteString) -> NeoResult<NeoArray<NeoValue>>

Returns properties/metadata for the given token.

Dyn Compatibility

This trait is dyn compatible.

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