Struct rusk_vm::NetworkState

pub struct NetworkState { /* fields omitted */ }

The main network state, includes the full state of contracts.

Implementations

impl NetworkState

pub fn with_block_height(block_height: u64) -> Self

Returns a NetworkState for a specific block height

pub fn deploy(&mut self, contract: Contract) -> Result<ContractId, CanonError>

Deploys a contract to the state, returns the address of the created contract or an error

pub fn get_contract<'a>(
    &'a self,
    contract_id: &ContractId
) -> Result<impl Deref<Target = Contract> + 'a, VMError>

Returns a reference to the specified contracts state

pub fn get_contract_mut<'a>(
    &'a mut self,
    contract_id: &ContractId
) -> Result<impl DerefMut<Target = Contract> + 'a, VMError>

Returns a reference to the specified contracts state

pub fn modules(&self) -> &Rc<RefCell<HashMap<ContractId, Box<dyn HostModule>>>>

Returns a reference to the map of registered host modules

pub fn block_height(&self) -> u64

Returns the state’s block height

pub fn query<A, R>(
    &mut self,
    target: ContractId,
    query: A,
    gas_meter: &mut GasMeter
) -> Result<R, VMError> where
    A: Canon,
    R: Canon, 

Queryn the contract at address target

pub fn transact<A, R>(
    &mut self,
    target: ContractId,
    transaction: A,
    gas_meter: &mut GasMeter
) -> Result<R, VMError> where
    A: Canon,
    R: Canon, 

Transact with the contract at address target

pub fn register_host_module<M>(&mut self, module: M) where
    M: HostModule + 'static, 

Register a host-fn handler

pub fn get_contract_cast_state<C>(
    &self,
    contract_id: &ContractId
) -> Result<C, VMError> where
    C: Canon, 

Gets the state of the given contract

Trait Implementations

impl Canon for NetworkState

fn encode(&self, sink: &mut Sink<'_>)

fn encoded_len(&self) -> usize

Returns the number of bytes needed to encode this value

impl Clone for NetworkState

fn clone(&self) -> NetworkState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for NetworkState

fn default() -> NetworkState

Returns the “default value” for a type.
