Struct BlobSparseStorage 

pub struct BlobSparseStorage<S: BlobStore> { /* private fields */ }

Blob storage: shard i is the SparseHandle namespace Sparse_{name}/shard_{i}, root files live under Sparse_{name}. The local cache under cache_base is disposable; the store is the truth.

Implementations

impl<S: BlobStore> BlobSparseStorage<S>

pub fn new( store: Arc<S>, name: impl Into<String>, cache_base: impl Into<PathBuf>, ) -> Self
