Struct DumbSnapshotter

pub struct DumbSnapshotter { /* private fields */ }

Snapshotter that does nothing. It is mainly used for test purposes.

Implementations

impl DumbSnapshotter

pub fn new(compression_algorithm: CompressionAlgorithm) -> Self

Create a new instance of DumbSnapshotter.

The compression_algorithm parameter is used for the output file name extension.

pub fn with_archive_size(self, size: u64) -> Self

Set the size assigned to the produced snapshots.

pub fn get_last_snapshot(&self) -> StdResult<Option<FileArchive>>

Return the last fake snapshot produced.

fn compression_algorithm(&self) -> CompressionAlgorithm

Return the compression algorithm used by the snapshotter.
