Struct FakeSnapshotter

pub struct FakeSnapshotter { /* private fields */ }

Snapshotter that writes empty files to the filesystem. Used for testing purposes.

Implementations

impl FakeSnapshotter

pub fn new<T: AsRef<Path>>(work_dir: T) -> Self

FakeSnapshotter factory, with a default compression algorithm of Gzip.

pub fn with_compression_algorithm( self, compression_algorithm: CompressionAlgorithm, ) -> Self

Set the compression algorithm used to for the output file name extension.
