Struct LocalStorageBackend 

pub struct LocalStorageBackend { /* private fields */ }

Local filesystem storage backend

This is the default storage backend that stores files on the local filesystem using a content-addressed structure based on hash prefixes.

Implementations

impl LocalStorageBackend

pub fn new(data_dir: PathBuf) -> Self

Create a new local storage backend

pub fn data_dir(&self) -> &Path

Get the data directory
