Struct AtomicFileStage 

pub struct AtomicFileStage { /* private fields */ }

One unpublished file whose destination is chosen after its bytes have been written. This is the streaming counterpart to write_atomic: callers can compute a content address while implementing std::io::Write, then commit the completed file under that address with the owning durability policy’s file-sync, rename, and directory-sync sequence.

Implementations

impl AtomicFileStage

pub fn create_in(parent: &Path) -> Result<Self, Error>

pub fn commit(self, destination: &Path) -> Result<(), WriteError<FileError>>

Trait Implementations

impl Write for AtomicFileStage

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

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
