Struct language_e2e_tests::data_store::FakeDataStore
source · pub struct FakeDataStore { /* private fields */ }
Expand description
An in-memory implementation of StateView
and [RemoteCache
] for the VM.
Tests use this to set up state, and pass in a reference to the cache whenever a StateView
or
RemoteCache
is needed.
Implementations§
source§impl FakeDataStore
impl FakeDataStore
sourcepub fn new(data: HashMap<AccessPath, Vec<u8>>) -> Self
pub fn new(data: HashMap<AccessPath, Vec<u8>>) -> Self
Creates a new FakeDataStore
with the provided initial data.
sourcepub fn add_write_set(&mut self, write_set: &WriteSet)
pub fn add_write_set(&mut self, write_set: &WriteSet)
Adds a WriteSet
to this data store.
sourcepub fn set(
&mut self,
access_path: AccessPath,
data_blob: Vec<u8>
) -> Option<Vec<u8>>
pub fn set( &mut self, access_path: AccessPath, data_blob: Vec<u8> ) -> Option<Vec<u8>>
Sets a (key, value) pair within this data store.
Returns the previous data if the key was occupied.
sourcepub fn remove(&mut self, access_path: &AccessPath) -> Option<Vec<u8>>
pub fn remove(&mut self, access_path: &AccessPath) -> Option<Vec<u8>>
Deletes a key from this data store.
Returns the previous data if the key was occupied.
sourcepub fn add_account_data(&mut self, account_data: &AccountData)
pub fn add_account_data(&mut self, account_data: &AccountData)
Adds an AccountData
to this data store.
sourcepub fn add_module(&mut self, module_id: &ModuleId, blob: Vec<u8>)
pub fn add_module(&mut self, module_id: &ModuleId, blob: Vec<u8>)
Adds a [CompiledModule
] to this data store.
Does not do any sort of verification on the module.

fn get(&self, access_path: &AccessPath) -> Result<Option<Vec<u8>>>
Gets the state for a single access path.
source§fn is_genesis(&self) -> bool
fn is_genesis(&self) -> bool
VM needs this method to know whether the current state view is for genesis state creation.
Currently TransactionPayload::WriteSet is only valid for genesis state creation.
source§fn id(&self) -> StateViewId
fn id(&self) -> StateViewId
For logging and debugging purpose, identifies what this view is for.
