Implementations

impl Backend

pub fn init(&self, compression: Compression) -> Result<bool>

Initialize the backend storage Idempotent: returns true if the backend was already initialized.

pub fn check_access(&self) -> Result<()>

Check that the current user can access the backend. Called once before batch operations so auth/permission problems fail fast with a single error instead of once per file.

pub fn store(&self, req: StoreRequest<'_>) -> Result<StoreResult>

Store file to backend under req.hashes, compressing it. The source is passed uncompressed, the hash we send is only for (optional) verification by a server

pub fn retrieve(&self, req: RetrieveRequest<'_>) -> Result<bool>

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

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

Check if the file exists in the backend

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

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

pub fn get_audit_entries(&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
