Required Methods

fn import_file( &self, data: PathBuf, mode: ImportMode, format: BlobFormat, progress: impl ProgressSender<Msg = ImportProgress> + IdGenerator ) -> impl Future<Output = Result<(TempTag, u64)>> + Send

This trait method imports a file from a local path.

data is the path to the file. mode is a hint how the file should be imported. progress is a sender that provides a way for the importer to send progress messages when importing large files. This also serves as a way to cancel the import. If the consumer of the progress messages is dropped, subsequent attempts to send progress will fail.

Returns the hash of the imported file. The reason to have this method is that some database implementations might be able to import a file without copying it.

fn import_bytes( &self, bytes: Bytes, format: BlobFormat ) -> impl Future<Output = Result<TempTag>> + Send

Import data from memory.

It is a special case of import that does not use the file system.

fn import_stream( &self, data: impl Stream<Item = Result<Bytes>> + Send + Unpin + 'static, format: BlobFormat, progress: impl ProgressSender<Msg = ImportProgress> + IdGenerator ) -> impl Future<Output = Result<(TempTag, u64)>> + Send

Import data from a stream of bytes.

fn set_tag( &self, name: Tag, hash: Option<HashAndFormat> ) -> impl Future<Output = Result<()>> + Send

Set a tag

fn create_tag( &self, hash: HashAndFormat ) -> impl Future<Output = Result<Tag>> + Send

Create a new tag

fn temp_tag(&self, value: HashAndFormat) -> TempTag

Create a temporary pin for this store

fn gc_run<G, Gut>( &self, config: GcConfig, protected_cb: G ) -> impl Future<Output = ()>

where G: Fn() -> Gut, Gut: Future<Output = BTreeSet<Hash>> + Send,

Start the GC loop

The gc task will shut down, when dropping the returned future.

fn delete(&self, hashes: Vec<Hash>) -> impl Future<Output = Result<()>> + Send

physically delete the given hashes from the store.

fn shutdown(&self) -> impl Future<Output = ()> + Send

Shutdown the store.

fn sync(&self) -> impl Future<Output = Result<()>> + Send

Sync the store.

Provided Methods

fn import_reader( &self, data: impl AsyncRead + Send + Unpin + 'static, format: BlobFormat, progress: impl ProgressSender<Msg = ImportProgress> + IdGenerator ) -> impl Future<Output = Result<(TempTag, u64)>> + Send

Import data from an async byte reader.

fn validate( &self, repair: bool, tx: BoxedProgressSender<ValidateProgress> ) -> impl Future<Output = Result<()>> + Send

Validate the database

This will check that the file and outboard content is correct for all complete entries, and output valid ranges for all partial entries.

It will not check the internal consistency of the database.

Object Safety

This trait is not object safe.
