Struct RealFileSystem 

pub struct RealFileSystem;

Reads and writes the actual filesystem. Stateless, so it is cheap to share across the worker thread and any future services that need it.

Implementations

impl RealFileSystem

pub const fn new() -> Self

Trait Implementations

impl Clone for RealFileSystem

fn clone(&self) -> RealFileSystem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RealFileSystem

impl Debug for RealFileSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RealFileSystem

fn default() -> RealFileSystem

Returns the “default value” for a type.

impl FileSystemService for RealFileSystem

fn read_dir(&self, path: &Path) -> FsResult<Vec<DirEntryInfo>>

List one directory level. Does not recurse — the tree is lazy (ADR-0005 §2).

fn read_file(&self, path: &Path) -> FsResult<Vec<u8>>

fn create_file(&self, path: &Path) -> FsResult<()>

Create an empty file. Errors with FsError::AlreadyExists rather than truncating.

fn write_file(&self, path: &Path, contents: &[u8]) -> FsResult<()>

Replace a file’s contents, creating it if absent.

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

Create a directory, including missing parents.

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

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

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

Recursively delete a directory. Named for what it does: callers must confirm with the user (or hold an agent permission grant) before invoking it.

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

Resolve symlinks and .. to an absolute path. Used as the loop guard when deciding whether a symlinked directory has already been visited.
