}Expand description
Abstracts away the borrowing of a managed types structure.
Required Methods§
Sourceunsafe fn memory_load(&self, offset: MemPtr, length: MemLength) -> Vec<u8> ⓘ
unsafe fn memory_load(&self, offset: MemPtr, length: MemLength) -> Vec<u8> ⓘ
Loads a slice of memory from the instance.
§Safety
The offset and the length must point to valid instance memory.
Sourceunsafe fn memory_store(&self, mem_ptr: MemPtr, data: &[u8])
unsafe fn memory_store(&self, mem_ptr: MemPtr, data: &[u8])
fn m_types_lock(&self) -> MutexGuard<'_, ManagedTypeContainer>
fn gas_schedule(&self) -> &GasSchedule
fn use_gas(&mut self, gas: u64) -> Result<(), VMHooksEarlyExit>
fn input_ref(&self) -> &TxInput
Sourcefn random_next_bytes(&self, length: usize) -> Vec<u8> ⓘ
fn random_next_bytes(&self, length: usize) -> Vec<u8> ⓘ
Random number generator, based on the blockchain randomness source.
fn result_lock(&self) -> MutexGuard<'_, TxResult>
fn storage_read_any_address(&self, address: &VMAddress, key: &[u8]) -> Vec<u8> ⓘ
fn storage_write( &mut self, key: &[u8], value: &[u8], ) -> Result<(), VMHooksEarlyExit>
fn get_block_config(&self) -> &BlockConfig
fn back_transfers_lock(&self) -> MutexGuard<'_, BackTransfers>
Sourcefn account_data(&self, address: &VMAddress) -> Option<AccountData>
fn account_data(&self, address: &VMAddress) -> Option<AccountData>
For ownership reasons, needs to return a clone.
Can be optimized, but is not a priority right now.
