Struct FsBackend 

pub struct FsBackend { /* private fields */ }

Filesystem-rooted Storage implementation.

Implementations

impl FsBackend

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

Create a new backend rooted at root. The directory must exist or be creatable; this call ensures it exists.

pub fn root(&self) -> &Path

Return the root directory.

Trait Implementations

impl Clone for FsBackend

fn clone(&self) -> FsBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
