Struct era_test_node::fork::ForkStorage

pub struct ForkStorage<S> {
    pub inner: Arc<RwLock<ForkStorageInner<S>>>,
    pub chain_id: L2ChainId,
}

In memory storage, that allows ‘forking’ from other network. If forking is enabled, it reads missing data from remote location. S - is a struct that is used for source of the fork.

Fields

inner: Arc<RwLock<ForkStorageInner<S>>>

chain_id: L2ChainId

Implementations

impl<S: ForkSource> ForkStorage<S>

pub fn new( fork: Option<ForkDetails>, system_contracts_options: &Options ) -> Self

pub fn get_cache_config(&self) -> Result<CacheConfig, String>

pub fn get_fork_url(&self) -> Result<String, String>

pub fn read_value_internal(&self, key: &StorageKey) -> Result<StorageValue>

pub fn load_factory_dep_internal(&self, hash: H256) -> Result<Option<Vec<u8>>>

pub fn is_write_initial_internal(&self, key: &StorageKey) -> Result<bool>

Check if this is the first time when we’re ever writing to this key. This has impact on amount of pubdata that we have to spend for the write.

impl<S> ForkStorage<S>

pub fn set_value(&mut self, key: StorageKey, value: StorageValue)

pub fn store_factory_dep(&mut self, hash: H256, bytecode: Vec<u8>)

Trait Implementations

impl<S: Clone> Clone for ForkStorage<S>

fn clone(&self) -> ForkStorage<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for ForkStorage<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: Debug + ForkSource> ReadStorage for &ForkStorage<S>

fn read_value(&mut self, key: &StorageKey) -> StorageValue

Read value of the key.

fn is_write_initial(&mut self, key: &StorageKey) -> bool

Checks whether a write to this storage at the specified key would be an initial write. Roughly speaking, this is the case when the storage doesn’t contain key, although in case of mutable storage, the caveats apply (a write to a key that is present in the storage but was not committed is still an initial write).

fn load_factory_dep(&mut self, hash: H256) -> Option<Vec<u8>>

Load the factory dependency code by its hash.

fn get_enumeration_index(&mut self, key: &StorageKey) -> Option<u64>

Retrieves the enumeration index for a given key.

fn is_bytecode_known(&mut self, bytecode_hash: &H256) -> bool

Returns whether a bytecode hash is “known” to the system.

impl<S: Debug + ForkSource> ReadStorage for ForkStorage<S>

fn is_write_initial(&mut self, key: &StorageKey) -> bool

Checks whether a write to this storage at the specified key would be an initial write. Roughly speaking, this is the case when the storage doesn’t contain key, although in case of mutable storage, the caveats apply (a write to a key that is present in the storage but was not committed is still an initial write).

fn load_factory_dep(&mut self, hash: H256) -> Option<Vec<u8>>

Load the factory dependency code by its hash.

fn read_value(&mut self, key: &StorageKey) -> StorageValue

Read value of the key.

fn get_enumeration_index(&mut self, key: &StorageKey) -> Option<u64>

Retrieves the enumeration index for a given key.

fn is_bytecode_known(&mut self, bytecode_hash: &H256) -> bool

Returns whether a bytecode hash is “known” to the system.
