Type Definition casper_engine_test_support::LmdbWasmTestBuilder

pub type LmdbWasmTestBuilder = WasmTestBuilder<LmdbGlobalState>;

Wasm test builder where state is held in LMDB.

Implementations

impl LmdbWasmTestBuilder

pub fn new_with_config<T: AsRef<OsStr> + ?Sized>(
    data_dir: &T,
    engine_config: EngineConfig
) -> Self

Returns an LmdbWasmTestBuilder with configuration.

pub fn flush_environment(&self)

Flushes the LMDB environment to disk.

pub fn new<T: AsRef<OsStr> + ?Sized>(data_dir: &T) -> Self

Returns a new LmdbWasmTestBuilder.

pub fn open<T: AsRef<OsStr> + ?Sized>(
    data_dir: &T,
    engine_config: EngineConfig,
    post_state_hash: Digest
) -> Self

Creates a new instance of builder using the supplied configurations, opening wrapped LMDBs (e.g. in the Trie and Data stores) rather than creating them.

pub fn open_raw<T: AsRef<Path>>(
    global_state_dir: T,
    engine_config: EngineConfig,
    post_state_hash: Digest
) -> Self

Creates a new instance of builder using the supplied configurations, opening wrapped LMDBs (e.g. in the Trie and Data stores) rather than creating them. Differs from open in that it doesn’t append GLOBAL_STATE_DIR to the supplied path.

pub fn lmdb_on_disk_size(&self) -> Option<u64>

Returns the file size on disk of the backing lmdb file behind LmdbGlobalState.

pub fn scratch_exec_and_commit(
    &mut self,
    exec_request: ExecuteRequest
) -> &mut Self

Execute and commit transforms from an ExecuteRequest into a scratch global state. You MUST call write_scratch_to_lmdb to flush these changes to LmdbGlobalState.

pub fn write_scratch_to_db(&mut self) -> &mut Self

Commit scratch to global state, and reset the scratch cache.

pub fn step_with_scratch(&mut self, step_request: StepRequest) -> &mut Self

run step against scratch global state.
