pub struct File { /* private fields */ }

RAII file handle.

Implementations

impl File

pub fn open(path: &[u8], flags: i32) -> Result<Self>

Open a file. path must be \0-terminated.

pub fn read(&self, buf: &mut [u8]) -> Result<usize>

Read from the file into buf. Returns the number of bytes read.

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

Write buf to the file. Returns the number of bytes written.

Trait Implementations

impl Drop for File

fn drop(&mut self)

Executes the destructor for this type.

impl ErrorType for File

type Error = Error

Error type of all the IO operations on this type.

impl Read for File

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

Read some bytes from this source into the specified buffer, returning how many bytes were read.

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

Read the exact number of bytes required to fill buf.

impl Write for File

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

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

fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, blocking until all intermediately buffered contents reach their destination.

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

Write an entire buffer into this writer.

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

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