}Expand description
Standard smart contract module for managing a single ESDT.
When added to a smart contract offers basic ESDT usage. A lot of contracts use an owned ESDT for various purposes. This module is used to offer a standard way of performing the basic operations.
It provides endpoints for:
- issuing of an ESDT
- setting local roles
- minting/burning
Required Methods§
fn token_id(&self) -> SingleValueMapper<Self::Api, TokenIdentifier<Self::Api>>
fn callbacks(&self) -> CallbackProxyObj<Self::Api>
Provided Methods§
fn issue_token( &self, token_display_name: ManagedBuffer<Self::Api>, token_ticker: ManagedBuffer<Self::Api>, token_type: EsdtTokenType, opt_num_decimals: OptionalValue<usize>, )
fn issue_callback( &self, result: ManagedAsyncCallResult<Self::Api, TokenIdentifier<Self::Api>>, )
fn mint(&self, token_nonce: u64, amount: &BigUint<Self::Api>)
fn burn(&self, token_nonce: u64, amount: &BigUint<Self::Api>)
fn nft_create<T: TopEncode>( &self, amount: &BigUint<Self::Api>, attributes: &T, ) -> u64
fn get_token_attributes<T: TopDecode>(&self, token_nonce: u64) -> T
fn require_token_issued(&self)
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
