API that groups methods that either send REWA or DCDT, or that call other contracts.

Required Methods

fn direct_rewa<D>( &self, to: &ManagedAddress<Self>, amount: &BigUint<Self>, data: D, )

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

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

fn direct_rewa_execute( &self, to: &ManagedAddress<Self>, amount: &BigUint<Self>, gas_limit: u64, endpoint_name: &ManagedBuffer<Self>, arg_buffer: &ManagedArgBuffer<Self>, ) -> Result<(), &'static [u8]>

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

fn direct_dcdt_execute( &self, to: &ManagedAddress<Self>, token: &TokenIdentifier<Self>, amount: &BigUint<Self>, gas_limit: u64, endpoint_name: &ManagedBuffer<Self>, arg_buffer: &ManagedArgBuffer<Self>, ) -> Result<(), &'static [u8]>

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

fn direct_dcdt_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 DCDT NFT to an address and executes like an async call, but without callback.

fn direct_multi_dcdt_transfer_execute( &self, to: &ManagedAddress<Self>, payments: &ManagedVec<Self, DcdtTokenPayment<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.

The data is expected to be of the form functionName@<arg1-hex>@<arg2-hex>@.... Use a HexCallDataSerializer to prepare this field.

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_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, address: &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, address: &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 Andes 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, address: &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, address: &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_dcdt_built_in_function( &self, gas: u64, endpoint_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.

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.
