Trait Implementations
impl BufRead for Empty
[src]
impl BufRead for Empty
[src]pub fn fill_buf(&mut self) -> Result<&[u8], Error>
[src]
pub fn fill_buf(&mut self) -> Result<&[u8], Error>
[src]Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more
pub fn consume(&mut self, _n: usize)
[src]
pub fn consume(&mut self, _n: usize)
[src]Tells this buffer that amt
bytes have been consumed from the buffer,
so they should no longer be returned in calls to read
. Read more
fn read_until(
&mut self,
byte: u8,
buf: &mut Vec<u8, Global>
) -> Result<usize, Error>
[src]
fn read_until(
&mut self,
byte: u8,
buf: &mut Vec<u8, Global>
) -> Result<usize, Error>
[src]Read all bytes into buf
until the delimiter byte
or EOF is reached. Read more
fn read_line(&mut self, buf: &mut String) -> Result<usize, Error>
[src]
fn read_line(&mut self, buf: &mut String) -> Result<usize, Error>
[src]Read all bytes until a newline (the 0xA
byte) is reached, and append
them to the provided buffer. Read more
impl Read for Empty
[src]
impl Read for Empty
[src]pub fn read(&mut self, _buf: &mut [u8]) -> Result<usize, Error>
[src]
pub fn read(&mut self, _buf: &mut [u8]) -> Result<usize, Error>
[src]Pull some bytes from this source into the specified buffer, returning how many bytes were read. Read more
pub unsafe fn initializer(&self) -> Initializer
[src]
pub unsafe fn initializer(&self) -> Initializer
[src]read_initializer
)Determines if this Read
er can work with buffers of uninitialized
memory. Read more
fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>
1.36.0[src]
fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>
1.36.0[src]Like read
, except that it reads into a slice of buffers. Read more
fn is_read_vectored(&self) -> bool
[src]
fn is_read_vectored(&self) -> bool
[src]can_vector
)Determines if this Read
er has an efficient read_vectored
implementation. Read more
fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>
[src]
fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>
[src]Read all bytes until EOF in this source, placing them into buf
. Read more
fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>
[src]
fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>
[src]Read all bytes until EOF in this source, appending them to buf
. Read more
fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>
1.6.0[src]
fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>
1.6.0[src]Read the exact number of bytes required to fill buf
. Read more
fn by_ref(&mut self) -> &mut Self
[src]
fn by_ref(&mut self) -> &mut Self
[src]Creates a “by reference” adaptor for this instance of Read
. Read more
impl Seek for Empty
1.51.0[src]
impl Seek for Empty
1.51.0[src]pub fn seek(&mut self, _pos: SeekFrom) -> Result<u64, Error>
[src]
pub fn seek(&mut self, _pos: SeekFrom) -> Result<u64, Error>
[src]Seek to an offset, in bytes, in a stream. Read more
pub fn stream_len(&mut self) -> Result<u64, Error>
[src]
pub fn stream_len(&mut self) -> Result<u64, Error>
[src]seek_stream_len
)Returns the length of this stream (in bytes). Read more
