}

File system abstraction (IGFD IFileSystem-like).

This is a first incremental step; the API will expand as Places/devices, directory creation, symlink support, and async enumeration are added.

Required Methods

fn read_dir(&self, dir: &Path) -> Result<Vec<FsEntry>>

List entries of a directory.

fn canonicalize(&self, path: &Path) -> Result<PathBuf>

Canonicalize a path (best-effort absolute normalization).

fn metadata(&self, path: &Path) -> Result<FsMetadata>

Fetch minimal metadata for a path.

fn create_dir(&self, path: &Path) -> Result<()>

Create a directory.

fn rename(&self, from: &Path, to: &Path) -> Result<()>

Rename/move a path.

fn remove_file(&self, path: &Path) -> Result<()>

Remove a file.

fn remove_dir(&self, path: &Path) -> Result<()>

Remove an empty directory.

fn remove_dir_all(&self, path: &Path) -> Result<()>

Remove a directory and all of its contents (recursive).

fn copy_file(&self, from: &Path, to: &Path) -> Result<u64>

Copy a file.

Returns the number of bytes copied (mirrors std::fs::copy).
