Trait Implementations

impl Backend for LocalBackend

fn is_initialized(&self) -> Result<bool>

Check whether the backend has already been initialized.

fn init(&self) -> Result<()>

Initialize the backend storage (create directories, set permissions, etc.)

fn store( &self, hash: &Hashes, source: &Path, compression: Compression, on_bytes: Option<&(dyn Fn(u64) + Send + Sync)>, ) -> Result<u64>

Store file to backend by hash, optionally compressing. Returns the stored (compressed) size in bytes.

fn retrieve( &self, hash: &Hashes, target: &Path, compression: Compression, on_bytes: Option<&(dyn Fn(u64) + Send + Sync)>, ) -> Result<bool>

Retrieve content by hash to target path, optionally decompressing. Returns true if the file was copied to the target path.

fn exists(&self, hash: &Hashes) -> Result<bool>

Check if the file exists in the backend

fn remove(&self, hash: &Hashes) -> Result<()>

Remove content by hash (for rollback). Best-effort, may silently fail.

fn log_audit(&self, entry: &AuditEntry) -> Result<()>

Log an audit entry to the backend’s audit log.

fn read_audit_file(&self, files: &[PathBuf]) -> Result<Vec<AuditEntry>>

Read the whole audit file, filtered by the given file paths. If files is empty, return the full audit log

impl Clone for LocalBackend

fn clone(&self) -> LocalBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocalBackend

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LocalBackend

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LocalBackend

fn eq(&self, other: &LocalBackend) -> 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.

impl Serialize for LocalBackend

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
