Struct FsStore

pub struct FsStore { /* private fields */ }

A file based store.

A store can be created using load or load_with_opts. Load will use the default options and create the required directories, while load_with_opts allows you to customize the options and the location of the database. Both variants will create the database if it does not exist, and load an existing database if one is found at the configured location.

In addition to implementing the Store API via Deref, there are a few additional methods that are specific to file based stores, such as dump.

Implementations

impl FsStore

pub async fn load(root: impl AsRef<Path>) -> Result<Self>

Load or create a new store.

pub async fn load_with_opts( db_path: PathBuf, options: Options, ) -> Result<FsStore>

Load or create a new store with custom options, returning an additional sender for file store specific commands.

impl FsStore

pub async fn dump(&self) -> Result<()>

Methods from Deref<Target = Store>

pub fn tags(&self) -> &Tags

The tags API.

pub fn blobs(&self) -> &Blobs

The blobs API.

pub fn remote(&self) -> &Remote

API for getting blobs from a single remote node.

pub fn downloader(&self, endpoint: &Endpoint) -> Downloader

Create a downloader for more complex downloads.

Unlike the other APIs, this creates an object that has internal state, so don’t create it ad hoc but store it somewhere if you need it multiple times.

pub async fn sync_db(&self) -> RequestResult<()>

pub async fn shutdown(&self) -> Result<()>

Methods from Deref<Target = Blobs>

pub async fn batch(&self) -> Result<Batch<'_>>

pub async fn delete_with_opts( &self, options: DeleteOptions, ) -> RequestResult<()>

pub async fn delete( &self, hashes: impl IntoIterator<Item = impl Into<Hash>>, ) -> RequestResult<()>

pub fn add_slice(&self, data: impl AsRef<[u8]>) -> AddProgress<'_>

pub fn add_bytes(&self, data: impl Into<Bytes>) -> AddProgress<'_>

pub fn add_bytes_with_opts( &self, options: impl Into<AddBytesOptions>, ) -> AddProgress<'_>

pub fn add_path_with_opts( &self, options: impl Into<AddPathOptions>, ) -> AddProgress<'_>

pub fn add_path(&self, path: impl AsRef<Path>) -> AddProgress<'_>

pub async fn add_stream( &self, data: impl Stream<Item = Result<Bytes>> + Send + Sync + 'static, ) -> AddProgress<'_>

pub fn export_ranges( &self, hash: impl Into<Hash>, ranges: impl Into<RangeSet2<u64>>, ) -> ExportRangesProgress

pub fn export_ranges_with_opts( &self, options: ExportRangesOptions, ) -> ExportRangesProgress

pub fn export_bao_with_opts( &self, options: ExportBaoOptions, local_update_cap: usize, ) -> ExportBaoProgress

pub fn export_bao( &self, hash: impl Into<Hash>, ranges: impl Into<ChunkRanges>, ) -> ExportBaoProgress

pub async fn export_chunk( &self, hash: impl Into<Hash>, offset: u64, ) -> ExportBaoResult<Leaf>

Export a single chunk from the given hash, at the given offset.

pub async fn get_bytes(&self, hash: impl Into<Hash>) -> ExportBaoResult<Bytes>

Get the entire blob into a Bytes

This will run out of memory when called for very large blobs, so be careful!

pub fn observe(&self, hash: impl Into<Hash>) -> ObserveProgress

Observe the bitfield of the given hash.

pub fn observe_with_opts(&self, options: ObserveOptions) -> ObserveProgress

pub fn export_with_opts(&self, options: ExportOptions) -> ExportProgress

pub fn export( &self, hash: impl Into<Hash>, target: impl AsRef<Path>, ) -> ExportProgress

pub fn list(&self) -> BlobsListProgress

pub async fn status(&self, hash: impl Into<Hash>) -> Result<BlobStatus>

pub async fn has(&self, hash: impl Into<Hash>) -> Result<bool>
