fn is_read_vectored(&self) -> bool
can_vector

er has an efficient read_vectored
implementation. Read more
sourcefn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>
fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>
Read all bytes until EOF in this source, placing them into buf
. Read more
sourcefn read_to_string(&mut self, buf: &mut String) -> Result<usize>
fn read_to_string(&mut self, buf: &mut String) -> Result<usize>
Read all bytes until EOF in this source, appending them to buf
. Read more
sourcefn read_exact(&mut self, buf: &mut [u8]) -> Result<()>
fn read_exact(&mut self, buf: &mut [u8]) -> Result<()>
Read the exact number of bytes required to fill buf
. Read more
sourcefn read_buf(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>
fn read_buf(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>
read_buf
)Pull some bytes from this source into the specified buffer. Read more
sourcefn read_buf_exact(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>
fn read_buf_exact(&mut self, buf: &mut ReadBuf<'_>) -> Result<(), Error>
read_buf
)Read the exact number of bytes required to fill buf
. Read more
1.0.0 · sourcefn by_ref(&mut self) -> &mut Self
fn by_ref(&mut self) -> &mut Self
Creates a “by reference” adaptor for this instance of Read
. Read more
sourceimpl<'slice> ReadLayered for SliceReader<'slice>
impl<'slice> ReadLayered for SliceReader<'slice>
sourcefn read_with_status(&mut self, buf: &mut [u8]) -> Result<(usize, Status)>
fn read_with_status(&mut self, buf: &mut [u8]) -> Result<(usize, Status)>
Like Read::read
, but also returns a Status
.
sourcefn read_vectored_with_status(
&mut self,
bufs: &mut [IoSliceMut<'_>]
) -> Result<(usize, Status)>
fn read_vectored_with_status(
&mut self,
bufs: &mut [IoSliceMut<'_>]
) -> Result<(usize, Status)>
Like Read::read_vectored
, but also returns a Status
.
sourcefn read_exact_using_status(&mut self, buf: &mut [u8]) -> Result<Status>
fn read_exact_using_status(&mut self, buf: &mut [u8]) -> Result<Status>
Like Read::read_exact
, but uses read_with_status
to avoid
performing an extra read
at the end. Read more
sourcefn minimum_buffer_size(&self) -> usize
fn minimum_buffer_size(&self) -> usize
Some streams require a buffer of at least a certain size.
