Struct FsStore 

pub struct FsStore { /* private fields */ }

Filesystem-backed content-addressed blob and fenced root store.

Implementations

impl FsStore

pub fn open(root: impl AsRef<Path>) -> Result<Self, StoreError>

Opens or creates a store below root.

Errors

Returns an error if the directory layout cannot be created.

Trait Implementations

impl BlobStore for FsStore

fn put(&self, bytes: &[u8]) -> Result<BlobId, StoreError>

Stores bytes and returns their content id.

fn get(&self, id: &BlobId) -> Result<Option<Vec<u8>>, StoreError>

Loads bytes by id, returning None when missing.

fn contains(&self, id: &BlobId) -> Result<bool, StoreError>

Reports whether a blob is present.

fn delete(&self, id: &BlobId) -> Result<(), StoreError>

Deletes a blob during garbage collection. Missing blobs are ignored.

fn list(&self) -> Result<Vec<BlobId>, StoreError>

Lists all blob identifiers known to this backend.

fn modified_at(&self, id: &BlobId) -> Result<Option<SystemTime>, StoreError>

Returns the blob’s creation/last-modification time when available. Backends without timestamps return None, which conservatively keeps the blob whenever a non-zero retention window is active.

impl RootStore for FsStore

fn get_root(&self, name: &str) -> Result<Option<Vec<u8>>, StoreError>

Reads a root pointer.

fn cas_root( &self, name: &str, expected: Option<&[u8]>, new: &[u8], ) -> Result<(), StoreError>

Publishes a root only if the stored pointer equals expected.

fn delete_root(&self, name: &str) -> Result<(), StoreError>

Removes a root pointer. Missing roots are ignored.

fn list_roots(&self, prefix: &str) -> Result<Vec<String>, StoreError>

Lists root names beginning with prefix, in sorted order.
