Implementations§

Source§

impl Snapshot

Source

pub fn scan(&self) -> BlockIterator<'_> ⓘ

Returns an iterator that returns all the Blocks in the buffer.

Source

pub fn get_block( &self, index: BlockIndex, ) -> Result<ScannedBlock<'_, Unknown>, ReaderError>

Gets the block at the given |index|.

Source

pub fn try_once_from_vmo(source: &Vmo) -> Result<Snapshot, ReaderError>

Try to take a consistent snapshot of the given regular Inspect VMO once, without retrying if a concurrent write is in progress.

Returns a Snapshot on success or an Error if a consistent snapshot could not be taken.

Source

pub fn try_once_from_blob_vmo(source: &Vmo) -> Result<Snapshot, ReaderError>

Try to take a consistent snapshot of the given Blob VMO once, without retrying if a concurrent write is in progress.

Returns a Snapshot on success or an Error if a consistent snapshot could not be taken.

Source

pub fn try_from_blob_vmo(source: &Vmo) -> Result<Snapshot, ReaderError>

Try to take a consistent snapshot of the given Blob VMO, retrying up to SNAPSHOT_TRIES times if concurrent writes are detected.

Returns a Snapshot on success or an Error if a consistent snapshot could not be taken.
