Struct AtomicWriter 

pub struct AtomicWriter { /* private fields */ }

A streaming atomic write. Nothing is visible at the destination until commit; dropping an uncommitted writer removes its temp file. A process killed mid-write leaves only the temp file behind.

Implementations

impl AtomicWriter

pub fn create(target: &Path, options: AtomicOptions) -> Result<Self>

pub fn temp_path(&self) -> &Path

pub fn file_mut(&mut self) -> &mut File

pub fn write_all(&mut self, bytes: &[u8]) -> Result<()>

pub fn commit(self) -> Result<()>

Publish: flush, fsync, rename over the target, fsync the directory.

Trait Implementations

impl Debug for AtomicWriter

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

Formats the value using the given formatter.

impl Drop for AtomicWriter

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
