Struct PinnedFile 

pub struct PinnedFile { /* private fields */ }

A file a PinnedVersion holds in place: a table, a blob file or a compression dictionary.

Implementations

impl PinnedFile

pub fn id(&self) -> u64

The file’s id: the table, blob file or dictionary id it is named by.

pub fn level(&self) -> Option<usize>

The level a table sits in; None for a blob file or a dictionary.

pub fn path(&self) -> &Path

Where the file lies on the tree’s filesystem.

pub fn file_size(&self) -> Result<u64>

The file’s length in bytes.

Errors

Propagates the filesystem’s metadata failure.

pub fn open(&self) -> Result<Box<dyn FsFile>>

Opens the file for reading through the filesystem the tree uses for it, to stream it byte for byte.

Errors

Propagates the filesystem’s open failure.

pub fn heal_attestation(&self) -> Result<Option<PathBuf>>

The heal attestation lying beside a table, if it has one: the record of an in-place heal whose digest the version does not hold yet. Shipped beside the table (same name with .heal-attest appended), it lets the restored tree reconcile that table as the source would.

Errors

Propagates the filesystem’s probe failure.
