fn read(&self) -> Result<Option<LogReadResult<'_>>, Error>;
fn as_restarted(
&self,
) -> Result<Box<dyn ReadableJournal + Sync + Send>, Error>;
}Expand description
The snapshot capturer will take a series of objects that represents the state of a WASM process at a point in time and saves it so that it can be restored. It also allows for the restoration of that state at a later moment
Required Methods§
Sourcefn read(&self) -> Result<Option<LogReadResult<'_>>, Error>
fn read(&self) -> Result<Option<LogReadResult<'_>>, Error>
Returns a stream of snapshot objects that the runtime will use to restore the state of a WASM process to a previous moment in time
Sourcefn as_restarted(&self) -> Result<Box<dyn ReadableJournal + Sync + Send>, Error>
fn as_restarted(&self) -> Result<Box<dyn ReadableJournal + Sync + Send>, Error>
Resets the journal so that reads will start from the beginning again
