Struct tokio_fs::Stdin

pub struct Stdin { /* fields omitted */ }

A handle to the standard input stream of a process.

The handle implements the AsyncRead trait, but beware that concurrent reads of Stdin must be executed with care.

Created by the stdin function.

Trait Implementations

impl Debug for Stdin

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

Formats the value using the given formatter.

impl Read for Stdin

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.

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 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.

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 AsyncRead for Stdin

unsafe fn prepare_uninitialized_buffer(&self, _: &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>

Attempt to read from the AsyncRead into buf.

fn read_buf<B>(&mut self, buf: &mut B) -> Result<Async<usize>, Error> where     B: BufMut,

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

fn framed<T>(self, codec: T) -> Framed<Self, T> where     Self: AsyncWrite,     T: Decoder + Encoder,

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.

fn split(self) -> (ReadHalf<Self>, WriteHalf<Self>) where     Self: AsyncWrite,

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