Struct ObjectStoreReader 

pub struct ObjectStoreReader { /* private fields */ }

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

Trait Implementations

impl BlobChildren for ObjectStoreReader

fn children( &self, handle: Inline<Handle<UnknownBlob>>, ) -> Vec<Inline<Handle<UnknownBlob>>>

Return handles of blobs referenced by handle that exist in this store.

impl BlobStoreGet for ObjectStoreReader

type GetError<E: Error + Send + Sync + 'static> = GetBlobErr<E>

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

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

where S: BlobEncoding + 'static, T: TryFromBlob<S>, Handle<S>: InlineEncoding,

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 BlobStoreList for ObjectStoreReader

type Err = ListBlobsErr

Error type for listing operations.

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

Iterator over blob handles in the store.

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

Lists all blobs in the repository.

fn blobs_diff<'a>(&'a self, _old: &Self) -> Self::Iter<'a>

Lists blobs in self that are not in old.

impl BlobStoreMeta for ObjectStoreReader

type MetaError = Error

Error type returned by metadata calls.

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

where S: BlobEncoding + 'static, Handle<S>: InlineEncoding,

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

impl Clone for ObjectStoreReader

fn clone(&self) -> ObjectStoreReader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectStoreReader

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

Formats the value using the given formatter.

impl Eq for ObjectStoreReader

impl PartialEq for ObjectStoreReader

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.
