Trait Implementations

impl Read for Connection

[+]

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

[−]

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>

    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

fn by_ref(&mut self) -> &mut Self

[−]

    R: Read,  type Item = Result<char, CharsError>;

fn chars(self) -> Chars<Self>

[−]

Deprecated since 1.27.0

: Use str::from_utf8 instead: https://doc.rust-lang.org/nightly/std/str/struct.Utf8Error.html#examples

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

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an [Iterator] over [char]s.

Important traits for Take<T>

impl<T> Read for Take<T> where
    T: Read, 

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

[−]

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

impl AsyncRead for Connection

[+]

unsafe fn prepare_uninitialized_buffer(&self, buf: &mut [u8]) -> bool

[−]

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

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

[−]

Deprecated since 0.1.7

: Use tokio_codec::Decoder::framed instead

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

[−]

Helper method for splitting this read/write object into two halves.

impl Write for Connection
