Crate zksync_object_store 

This crate provides the object storage abstraction that allows to get, put and remove binary blobs. The following implementations are available:

• File-backed store saving blobs as separate files in the local filesystem
• GCS-based store
• Mock in-memory store

Normally, these implementations are not used directly. Instead, a store trait object (Arc<dyn ObjectStore>) can be constructed using an ObjectStoreFactory based on the configuration. This trait object is what should be used for dependency injection.

Besides the lower-level storage abstraction, the crate provides high-level typesafe <dyn ObjectStore>::get() and <dyn ObjectStore>::put() methods to store (de)serializable objects. Prefer using these methods whenever possible.

Re-exports

pub use bincode;

Macros

serialize_using_bincode

Derives StoredObject::serialize() and StoredObject::deserialize() using the bincode (de)serializer. Should be used in impl StoredObject blocks.

Structs

FileBackedObjectStore

ObjectStore implementation storing objects as files in a local filesystem. Mostly useful for local testing.

GoogleCloudStore

ObjectStore implementation based on GCS.

MockObjectStore

Mock ObjectStore implementation.

ObjectStoreFactory

Factory of ObjectStores that caches the store instance once it’s created. Used mainly for legacy reasons.

Enums

Bucket

Bucket for ObjectStore in which objects can be placed.

GoogleCloudStoreAuthMode

Authentication mode for GoogleCloudStore.

ObjectStoreError

Errors during ObjectStore operations.

Traits

ObjectStore

Functionality to fetch and store byte blobs from an object store (AWS S3, Google Cloud Storage, Azure Blobstore etc).

StoredObject

Object that can be stored in an ObjectStore.
