Struct ObjectStoreReader 

pub struct ObjectStoreReader<H> { /* private fields */ }

Read-only handle into an ObjectStoreRemote that can be cloned and shared.

Trait Implementations

impl<H> BlobStoreGet<H> for ObjectStoreReader<H>

where H: HashProtocol,

type GetError<E: Error> = GetBlobErr<E>

Error type for get operations, parameterised by the deserialization error.

fn get<T, S>( &self, handle: Value<Handle<H, S>>, ) -> Result<T, Self::GetError<<T as TryFromBlob<S>>::Error>>

where S: BlobSchema + 'static, T: TryFromBlob<S>, Handle<H, S>: ValueSchema,

Retrieves a blob from the repository by its handle. The handle is a unique identifier for the blob, and is used to retrieve it from the repository. The blob is returned as a Blob object, which contains the raw bytes of the blob, which can be deserialized via the appropriate schema type, which is specified by the T type parameter.

impl<H> BlobStoreList<H> for ObjectStoreReader<H>

where H: HashProtocol,

type Err = ListBlobsErr

Error type for listing operations.

type Iter<'a> = BlockingIter<Result<Value<Handle<H, UnknownBlob>>, <ObjectStoreReader<H> as BlobStoreList<H>>::Err>>

Iterator over blob handles in the store.

fn blobs<'a>(&'a self) -> Self::Iter<'a>

Lists all blobs in the repository.

impl<H> BlobStoreMeta<H> for ObjectStoreReader<H>

where H: HashProtocol,

type MetaError = Error

Error type returned by metadata calls.

fn metadata<S>( &self, handle: Value<Handle<H, S>>, ) -> Result<Option<BlobMetadata>, Self::MetaError>

where S: BlobSchema + 'static, Handle<H, S>: ValueSchema,

Returns metadata for the blob identified by handle, or None if the blob is not present.

impl<H: Clone> Clone for ObjectStoreReader<H>

fn clone(&self) -> ObjectStoreReader<H>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<H> Debug for ObjectStoreReader<H>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<H> PartialEq for ObjectStoreReader<H>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
