impl File

Methods added by fs-err that are not available on tokio::fs::File.

pub fn from_parts<P>(file: TokioFile, path: P) -> Self

where P: Into<PathBuf>,

Creates a File from a raw file and its path.

pub fn into_parts(self) -> (TokioFile, PathBuf)

Extract the raw file and its path from this File.

pub fn file(&self) -> &TokioFile

Returns a reference to the underlying tokio::fs::File.

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

Returns a mutable reference to the underlying tokio::fs::File.

pub fn path(&self) -> &Path

Returns a reference to the path that this file was created with.

Trait Implementations

impl AsRawFd for File

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl AsyncRead for File

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut ReadBuf<'_> ) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl AsyncSeek for File

fn start_seek(self: Pin<&mut Self>, position: SeekFrom) -> Result<()>

Attempts to seek to an offset, in bytes, in a stream.

fn poll_complete( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Result<u64>>

Waits for a seek operation to complete.

impl AsyncWrite for File

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8] ) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>] ) -> Poll<Result<usize>>

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

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl Debug for File

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

Formats the value using the given formatter.

impl From<File> for File

fn from(f: File) -> Self

Converts to this type from the input type.

impl From<File> for File

fn from(f: File) -> Self

Converts to this type from the input type.
