Struct SafeFileCreator 

pub struct SafeFileCreator { /* private fields */ }

Implementations

impl SafeFileCreator

pub fn new<P: AsRef<Path>>(dest_path: P) -> Result<Self>

Safely creates a new file at a specific location. Ensures the file is not created with elevated privileges, and a temporary file is created then renamed on close.

pub fn new_unnamed(temp_root: impl AsRef<Path>) -> Result<Self>

Safely creates a new file while a destination name can’t be decided now. Users need to call

pub fn set_dest_path<P: AsRef<Path>>(dest_path: P)

to set the destination before closing the file.

pub fn replace_existing<P: AsRef<Path>>(dest_path: P) -> Result<Self>

Safely replaces a new file at a specific location. Ensures the file is not created with elevated privileges, and additionally the metadata of the old one will match the new metadata.

pub fn set_dest_path<P: AsRef<Path>>(&mut self, dest_path: P)

pub fn abort(&mut self) -> Result<()>

pub fn close(&mut self) -> Result<()>

Closes the writer and replaces the original file with the temporary file

Trait Implementations

impl Drop for SafeFileCreator

fn drop(&mut self)

Executes the destructor for this type.

impl Seek for SafeFileCreator

fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seek to an offset, in bytes, in a stream.

fn rewind(&mut self) -> Result<(), Error>

Rewind to the beginning of a stream.

fn stream_len(&mut self) -> Result<u64, Error>

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

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

Returns the current seek position from the start of the stream.

fn seek_relative(&mut self, offset: i64) -> Result<(), Error>

Seeks relative to the current position.

impl Write for SafeFileCreator

fn write(&mut self, buf: &[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.
