Trait Implementations

impl<T: Buf> Buf for Take<T>

fn remaining(&self) -> usize

Returns the number of bytes that can be accessed from the Buf

fn bytes<'a>(&'a self) -> &'a [u8]

Returns a slice starting at the current Buf position and of length between 0 and Buf::remaining().

fn advance(&mut self, cnt: usize)

Advance the internal cursor of the Buf

fn has_remaining(&self) -> bool

Returns true if there are any more bytes to consume

fn read_slice(&mut self, dst: &mut [u8]) -> usize

Read bytes from the Buf into the given slice and advance the cursor by the number of bytes read. Returns the number of bytes read.

fn read_byte(&mut self) -> Option<u8>

Read a single byte from the Buf

impl<T: MutBuf> MutBuf for Take<T>

fn remaining(&self) -> usize

Returns the number of bytes that can be written to the MutBuf

unsafe fn mut_bytes<'a>(&'a mut self) -> &'a mut [u8]

Returns a mutable slice starting at the current MutBuf position and of length between 0 and MutBuf::remaining().

unsafe fn advance(&mut self, cnt: usize)

Advance the internal cursor of the MutBuf

fn has_remaining(&self) -> bool

Returns true iff there is any more space for bytes to be written

fn write_slice(&mut self, src: &[u8]) -> usize

Write bytes from the given slice into the MutBuf and advance the cursor by the number of bytes written. Returns the number of bytes written.

fn write_byte(&mut self, byte: u8) -> bool

Write a single byte to the MuBuf

impl<T: Debug> Debug for Take<T>

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

Formats the value using the given formatter.

impl<T: Buf> Read for Take<T>

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.
