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

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

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