Struct OsFs 

pub struct OsFs;

The operating system’s filesystem. No test can see whether a sync reached the disk without cutting power, so Store’s crash tests use the crash filesystem’s model of syncing instead.

Trait Implementations

impl Clone for OsFs

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OsFs

impl Debug for OsFs

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

Formats the value using the given formatter.

impl Default for OsFs

fn default() -> Self

Returns the “default value” for a type.

impl Fs for OsFs

fn write_new(&self, path: &Path, data: &[u8]) -> Result<()>

Creates a file that must not exist yet and writes data to it, without syncing.

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

Makes a file’s data durable.

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

Renames a file, replacing any file at to.

fn sync_dir(&self, dir: &Path) -> Result<()>

Makes a directory’s entries durable: files created, renamed or removed in it.

fn read(&self, path: &Path) -> Result<Vec<u8>>

Reads a whole file.

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

Removes a file.

fn list(&self, dir: &Path) -> Result<Vec<OsString>>

The names in a directory, sorted.

fn create_dir_all(&self, dir: &Path) -> Result<()>

Creates a directory and its parents, without syncing. A new directory survives a crash once the directory holding it is synced.

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

Removes a directory and everything in it, without syncing. The removal survives a crash once the directory that held it is synced.
