Struct FileBlobStore 

pub struct FileBlobStore { /* private fields */ }

Durable filesystem-backed blob store.

Blobs are stored under blobs/sha256/aa/bb/<cid-hex> below the configured root directory. Writes are content-addressed and idempotent; a completed write is published with an atomic rename inside the target directory.

Implementations

impl FileBlobStore

pub fn open(root: impl Into<PathBuf>) -> Result<Self, FileBlobStoreError>

Open or create a filesystem blob store rooted at root.

pub fn root(&self) -> &Path

Return the root directory for this blob store.

pub fn namespace_dir(&self) -> PathBuf

Return the namespace directory that contains sharded blob files.

pub fn path_for_ref(&self, reference: &BlobRef) -> PathBuf

Return the filesystem path for a blob reference.

Trait Implementations

impl BlobStore for FileBlobStore

type Error = FileBlobStoreError

Error type for blob storage operations.

fn get_blob(&self, reference: &BlobRef) -> Result<Option<Vec<u8>>, Self::Error>

Load a blob by reference.

fn put_blob(&self, bytes: &[u8]) -> Result<BlobRef, Self::Error>

Store bytes and return their content-addressed reference.

fn delete_blob(&self, reference: &BlobRef) -> Result<(), Self::Error>

Delete a blob. Deleting a missing blob is not an error.

impl BlobStoreScan for FileBlobStore

fn list_blob_refs(&self) -> Result<Vec<BlobRef>, Self::Error>

List all known blob references.

impl Clone for FileBlobStore

fn clone(&self) -> FileBlobStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileBlobStore

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

Formats the value using the given formatter.
