pub struct StorageEngine {
store: ChunkStoreHandle,
cache: QueryCacheHandle,
}
Expand description
Keeps track of handles towards a ChunkStore
and its QueryCache
.
A StorageEngine
doesn’t add any feature on top of what ChunkStoreHandle
and
QueryCacheHandle
already offer: the job of the StorageEngine
is to leverage the type
system in order to protect against deadlocks and race conditions at compile time.
The handles stored within will never be publicly accessible past construction.
The underlying ChunkStore
and QueryCache
can be accessed through one of the
following methods:
Fields§

source§impl StorageEngine
impl StorageEngine
sourcepub unsafe fn new(
store: ChunkStoreHandle,
cache: QueryCacheHandle,
) -> StorageEngine
pub unsafe fn new( store: ChunkStoreHandle, cache: QueryCacheHandle, ) -> StorageEngine
Creates a new StorageEngine
with the specified ChunkStore
and QueryCache
handles.
§Safety
It is the responsibility of the caller to make sure that the given handles have not escaped
anywhere else before constructing this type, otherwise the StorageEngine
cannot make
any safety guarantees.
