impl Read for File[+]

[+] Show hidden undocumented items

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

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

fn read_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>[−]

Like read, except that it reads into a slice of buffers.

unsafe fn initializer(&self) -> Initializer[−]

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

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>[−]

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>[−]

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self[−]

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>[−]

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, [−]

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>[−]

Creates an adaptor which will read at most limit bytes from it.

impl Seek for File[+]

[+] Show hidden undocumented items

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

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

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

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

Returns the length of this stream (in bytes).

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

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

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