Struct LocalFsBackend 

Source 
pub struct LocalFsBackend { /* private fields */ }
Expand description

A local-filesystem storage backend.

Stores objects as files under a configurable root directory. The object key is mapped directly to a path beneath the root, so keys containing / become subdirectories.

This backend is synchronous internally but presents the async CloudStorageBackend interface by wrapping I/O with tokio::task::spawn_blocking.

Implementations§

Source§

impl LocalFsBackend

Source

pub fn new(root: impl Into<PathBuf>) -> Result<Self, String>

Create a new LocalFsBackend rooted at root.

The directory is created if it does not already exist.
