Trait Implementations

impl Clone for MockedExternal

fn clone(&self) -> MockedExternal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for MockedExternal

fn default() -> MockedExternal

Returns the “default value” for a type.

impl External for MockedExternal

fn storage_set(&mut self, key: &[u8], value: &[u8]) -> Result<(), VMLogicError>

Write value to the key of the storage trie associated with the current account.

fn storage_get( &self, key: &[u8], _mode: StorageGetMode ) -> Result<Option<Box<dyn ValuePtr>>, VMLogicError>

Read key from the storage trie associated with the current account.

fn storage_remove(&mut self, key: &[u8]) -> Result<(), VMLogicError>

Removes the key from the storage trie associated with the current account.

fn storage_remove_subtree(&mut self, prefix: &[u8]) -> Result<(), VMLogicError>

Note: The method is currently unused and untested.

fn storage_has_key(&mut self, key: &[u8]) -> Result<bool, VMLogicError>

Check whether the key is present in the storage trie associated with the current account.

fn generate_data_id(&mut self) -> CryptoHash

fn get_trie_nodes_count(&self) -> TrieNodesCount

Returns amount of touched trie nodes by storage operations

fn validator_stake( &self, account_id: &AccountId ) -> Result<Option<Balance>, VMLogicError>

Returns the validator stake for given account in the current epoch. If the account is not a validator, returns None.

fn validator_total_stake(&self) -> Result<Balance, VMLogicError>

Returns total stake of validators in the current epoch.
