Implementations§

source§

impl<SA> TokenAttributesMapper<SA>
where SA: StorageReadApi + StorageWriteApi + ManagedTypeApi + ErrorApi + Clone + 'static,

source

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

source

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.

source

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

source

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

source

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

source

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

source

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