impl CallValueApi for UncallableApi

fn check_not_payable(&self)

fn moax_value(&self) -> BigUint<Self>

Retrieves the MOAX call value from the VM. Will return 0 in case of an DCT transfer (cannot have both MOAX and DCT transfer simultaneously).

fn dct_value(&self) -> BigUint<Self>

Retrieves the DCT call value from the VM. Will return 0 in case of an MOAX transfer (cannot have both MOAX and DCT transfer simultaneously).

fn token(&self) -> TokenIdentifier<Self>

Returns the call value token identifier of the current call. The identifier is wrapped in a TokenIdentifier object, to hide underlying logic.

fn dct_token_nonce(&self) -> u64

Returns the nonce of the received DCT token. Will return 0 in case of MOAX or fungible DCT transfer.

fn dct_token_type(&self) -> DctTokenType

Returns the DCT token type. Will return “Fungible” for MOAX.

Will return the MOAX call value, but also fail with an error if DCT is sent. Especially used in the auto-generated call value processing.

fn require_dct(&self, token: &[u8]) -> BigUint<Self>

Will return the DCT call value, but also fail with an error if MOAX or the wrong DCT token is sent. Especially used in the auto-generated call value processing.

fn payment_token_pair(&self) -> (BigUint<Self>, TokenIdentifier<Self>)

Returns both the call value (either MOAX or DCT) and the token identifier. Especially used in the `#[payable(“*”)] auto-generated snippets. The method might seem redundant, but there is such a hook in Arwen that might be used in this scenario in the future.

fn get_all_dct_transfers(&self) -> ManagedVec<Self, DctTokenPayment<Self>>

impl SendApi for UncallableApi

fn direct_moax<D>( &self, _to: &ManagedAddress<Self>, _amount: &BigUint<Self>, _data: D )

where D: ManagedInto<Self, ManagedBuffer<Self>>,

Sends MOAX to a given address, directly. Used especially for sending MOAX to regular accounts.

fn direct_moax_execute( &self, _to: &ManagedAddress<Self>, _amount: &BigUint<Self>, _gas_limit: u64, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> Result<(), &'static [u8]>

Sends MOAX to an address (optionally) and executes like an async call, but without callback.

fn direct_dct_execute( &self, _to: &ManagedAddress<Self>, _token: &TokenIdentifier<Self>, _amount: &BigUint<Self>, _gas: u64, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> Result<(), &'static [u8]>

Sends DCT to an address and executes like an async call, but without callback.

fn direct_dct_nft_execute( &self, _to: &ManagedAddress<Self>, _token: &TokenIdentifier<Self>, _nonce: u64, _amount: &BigUint<Self>, _gas_limit: u64, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> Result<(), &'static [u8]>

Sends DCT NFT to an address and executes like an async call, but without callback.

fn direct_multi_dct_transfer_execute( &self, _to: &ManagedAddress<Self>, _payments: &ManagedVec<Self, DctTokenPayment<Self>>, _gas_limit: u64, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> Result<(), &'static [u8]>

fn async_call_raw( &self, _to: &ManagedAddress<Self>, _amount: &BigUint<Self>, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> !

Sends an asynchronous call to another contract. Calling this method immediately terminates tx execution. Using it directly is generally discouraged.

fn deploy_contract( &self, _gas: u64, _amount: &BigUint<Self>, _code: &ManagedBuffer<Self>, _code_metadata: CodeMetadata, _arg_buffer: &ManagedArgBuffer<Self> ) -> (ManagedAddress<Self>, ManagedVec<Self, ManagedBuffer<Self>>)

Deploys a new contract in the same shard. Unlike async_call_raw, the deployment is synchronous and tx execution continues afterwards. Also unlike async_call_raw, it uses an argument buffer to pass arguments If the deployment fails, Option::None is returned

fn deploy_from_source_contract( &self, _gas: u64, _amount: &BigUint<Self>, _source_contract_address: &ManagedAddress<Self>, _code_metadata: CodeMetadata, _arg_buffer: &ManagedArgBuffer<Self> ) -> (ManagedAddress<Self>, ManagedVec<Self, ManagedBuffer<Self>>)

Deploys a new contract in the same shard by re-using the code of an already deployed source contract. The deployment is done synchronously and the new contract’s address is returned. If the deployment fails, Option::None is returned

fn upgrade_from_source_contract( &self, _sc_address: &ManagedAddress<Self>, _gas: u64, _amount: &BigUint<Self>, _source_contract_address: &ManagedAddress<Self>, _code_metadata: CodeMetadata, _arg_buffer: &ManagedArgBuffer<Self> )

fn upgrade_contract( &self, _sc_address: &ManagedAddress<Self>, _gas: u64, _amount: &BigUint<Self>, _code: &ManagedBuffer<Self>, _code_metadata: CodeMetadata, _arg_buffer: &ManagedArgBuffer<Self> )

Upgrades a child contract of the currently executing contract. The upgrade is synchronous, and the current transaction will fail if the upgrade fails. The child contract’s new init function will be called with the provided arguments

fn execute_on_dest_context_raw( &self, _gas: u64, _to: &ManagedAddress<Self>, _value: &BigUint<Self>, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> ManagedVec<Self, ManagedBuffer<Self>>

Same shard, in-line execution of another contract.

fn execute_on_dest_context_raw_custom_result_range<F>( &self, _gas: u64, _to: &ManagedAddress<Self>, _value: &BigUint<Self>, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self>, _range_closure: F ) -> ManagedVec<Self, ManagedBuffer<Self>>

where F: FnOnce(usize, usize) -> (usize, usize),

Same shard, in-line execution of another contract. Allows the contract to specify which result range to extract as sync call result. This is a workaround to handle nested sync calls. Please do not use this method unless there is absolutely no other option. Will be eliminated after some future Arwen hook redesign. range_closure takes the number of results before, the number of results after, and is expected to return the start index (inclusive) and end index (exclusive).

fn execute_on_dest_context_by_caller_raw( &self, _gas: u64, _to: &ManagedAddress<Self>, _value: &BigUint<Self>, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> ManagedVec<Self, ManagedBuffer<Self>>

fn execute_on_same_context_raw( &self, _gas: u64, _to: &ManagedAddress<Self>, _value: &BigUint<Self>, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> ManagedVec<Self, ManagedBuffer<Self>>

fn execute_on_dest_context_readonly_raw( &self, _gas: u64, _address: &ManagedAddress<Self>, _endpoint_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> ManagedVec<Self, ManagedBuffer<Self>>

fn storage_store_tx_hash_key(&self, _data: &ManagedBuffer<Self>)

Used to store data between async call and callback.

fn storage_load_tx_hash_key(&self) -> ManagedBuffer<Self>

Used to store data between async call and callback.

fn call_local_dct_built_in_function( &self, _gas: u64, _function_name: &ManagedBuffer<Self>, _arg_buffer: &ManagedArgBuffer<Self> ) -> ManagedVec<Self, ManagedBuffer<Self>>

Allows synchronously calling a local function by name. Execution is resumed afterwards. You should never have to call this function directly. Use the other specific methods instead.
