    SA: StorageMapperApi,
{ /* private fields */ }

Implementations

impl<SA> TokenAttributesMapper<SA, CurrentStorage>

where SA: StorageMapperApi,

pub fn set<T: TopEncode + TopDecode + NestedEncode + NestedDecode, M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, token_nonce: u64, attributes: &T, )

pub fn update<T: TopEncode + TopDecode + NestedEncode + NestedDecode, M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, token_nonce: u64, attributes: &T, )

Use carefully. Update should be used mainly when backed up by the protocol.

pub fn clear<T: TopEncode + TopDecode + NestedEncode + NestedDecode, M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, token_nonce: u64, )

impl<SA, A> TokenAttributesMapper<SA, A>

where SA: StorageMapperApi, A: StorageAddress<SA>,

pub fn has_attributes<M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, token_nonce: u64, ) -> bool

pub fn has_nonce<T: TopEncode + TopDecode + NestedEncode + NestedDecode, M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, attr: &T, ) -> bool

pub fn get_attributes<T: TopEncode + TopDecode + NestedEncode + NestedDecode, M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, token_nonce: u64, ) -> T

pub fn get_nonce<T: TopEncode + TopDecode + NestedEncode + NestedDecode, M: ManagedTypeApi>( &self, token_id: &TokenIdentifier<M>, attr: &T, ) -> u64
