Implementations

impl<SA> FungibleTokenMapper<SA>where SA: StorageMapperApi + CallTypeApi,

pub fn issue( &self, issue_cost: BigUint<SA>, token_display_name: ManagedBuffer<SA>, token_ticker: ManagedBuffer<SA>, initial_supply: BigUint<SA>, num_decimals: usize, opt_callback: Option<CallbackClosure<SA>> ) -> !

Important: If you use custom callback, remember to save the token ID in the callback and clear the mapper in case of error! Clear is unusable outside this specific case.

#[callback] fn my_custom_callback( &self, #[call_result] result: ManagedAsyncCallResult<()>, ) { match result { ManagedAsyncCallResult::Ok(token_id) => { self.fungible_token_mapper().set_token_id(token_id); }, ManagedAsyncCallResult::Err(_) => { self.fungible_token_mapper().clear(); }, }

If you want to use default callbacks, import the default_issue_callbacks::DefaultIssueCallbacksModule from multiversx-sc-modules and pass None for the opt_callback argument

pub fn issue_and_set_all_roles( &self, issue_cost: BigUint<SA>, token_display_name: ManagedBuffer<SA>, token_ticker: ManagedBuffer<SA>, num_decimals: usize, opt_callback: Option<CallbackClosure<SA>> ) -> !

Trait Implementations

impl<SA> StorageMapper<SA> for FungibleTokenMapper<SA>where SA: StorageMapperApi + CallTypeApi,

fn new(base_key: StorageKey<SA>) -> Self

Will be called automatically by the #[storage_mapper] annotation generated code.

impl<SA> StorageTokenWrapper<SA> for FungibleTokenMapper<SA>where SA: StorageMapperApi + CallTypeApi,

fn get_storage_key(&self) -> ManagedRef<'_, SA, StorageKey<SA>>

fn get_token_state(&self) -> TokenMapperState<SA>

fn get_token_id(&self) -> TokenIdentifier<SA>

fn get_token_id_ref(&self) -> &TokenIdentifier<SA>

fn set_token_id(&mut self, token_id: TokenIdentifier<SA>)

fn is_empty(&self) -> bool

fn set_if_empty(&mut self, token_id: TokenIdentifier<SA>)

fn require_issued_or_set(&self)

fn require_same_token(&self, expected_token_id: &TokenIdentifier<SA>)

fn require_all_same_token( &self, payments: &ManagedVec<SA, EsdtTokenPayment<SA>> )

fn set_local_roles_for_address( &self, address: &ManagedAddress<SA>, roles: &[EsdtLocalRole], opt_callback: Option<CallbackClosure<SA>> ) -> !

fn get_sc_address() -> ManagedAddress<SA>

impl<SA> TopEncodeMulti for FungibleTokenMapper<SA>where SA: StorageMapperApi + CallTypeApi,

fn multi_encode_or_handle_err<O, H>( &self, output: &mut O, h: H ) -> Result<(), H::HandledErr>where O: TopEncodeMultiOutput, H: EncodeErrorHandler,

Version of top_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn multi_encode<O>(&self, output: &mut O) -> Result<(), EncodeError>where O: TopEncodeMultiOutput,

Attempt to serialize the value to ouput.

impl<SA> TypeAbi for FungibleTokenMapper<SA>where SA: StorageMapperApi + CallTypeApi,

fn type_name() -> TypeName

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC )

A type can provide more than its own description. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
