Struct conserve::test_fixtures::ScratchArchive

pub struct ScratchArchive { /* private fields */ }

A temporary archive, deleted when it goes out of scope.

The ScratchArchive can be treated as an Archive.

Implementations

impl ScratchArchive

pub fn new() -> ScratchArchive

pub fn path(&self) -> &Path

pub fn setup_incomplete_empty_band(&self)

pub fn store_two_versions(&self)

pub fn transport(&self) -> &dyn Transport

Methods from Deref<Target = Archive>

pub fn block_dir(&self) -> &BlockDir

pub fn band_exists(&self, band_id: BandId) -> Result<bool>

pub fn band_is_closed(&self, band_id: BandId) -> Result<bool>

pub fn iter_entries( &self, band_selection: BandSelectionPolicy, subtree: Apath, exclude: Exclude ) -> Result<impl Iterator<Item = IndexEntry>>

Return an iterator of entries in a selected version.

pub fn list_band_ids(&self) -> Result<Vec<BandId>>

Returns a vector of band ids, in sorted order from first to last.

pub fn resolve_band_id( &self, band_selection: BandSelectionPolicy ) -> Result<BandId>

pub fn open_stored_tree( &self, band_selection: BandSelectionPolicy ) -> Result<StoredTree>

pub fn last_band_id(&self) -> Result<Option<BandId>>

Return the BandId of the highest-numbered band, or Ok(None) if there are no bands, or an Err if any occurred reading the directory.

pub fn last_complete_band(&self) -> Result<Option<Band>>

Return the last completely-written band id, if any.

pub fn referenced_blocks( &self, band_ids: &[BandId], monitor: Arc<dyn Monitor> ) -> Result<HashSet<BlockHash>>

Returns all blocks referenced by all bands.

Shows a progress bar as they’re collected.

pub fn unreferenced_blocks( &self, monitor: Arc<dyn Monitor> ) -> Result<impl ParallelIterator<Item = BlockHash>>

Returns an iterator of blocks that are present and referenced by no index.

pub fn delete_bands( &self, delete_band_ids: &[BandId], options: &DeleteOptions, monitor: Arc<dyn Monitor> ) -> Result<DeleteStats>

Delete bands, and the blocks that they reference.

If delete_band_ids is empty, this deletes no bands, but will delete any garbage blocks referenced by no existing bands.

pub fn validate( &self, options: &ValidateOptions, monitor: Arc<dyn Monitor> ) -> Result<()>

Walk the archive to check all invariants.

If problems are found, they are emitted as warn or error level tracing messages. This function only returns an error if validation stops due to a fatal error.

Trait Implementations

impl AsRef<Archive> for ScratchArchive

fn as_ref(&self) -> &Archive

Converts this type into a shared reference of the (usually inferred) input type.

impl Default for ScratchArchive

fn default() -> Self

Returns the “default value” for a type.

impl Deref for ScratchArchive

fn deref(&self) -> &Archive

ScratchArchive can be directly used as an archive.

type Target = Archive

The resulting type after dereferencing.
