Struct sgx_tstd::io::Stdin

pub struct Stdin { /* fields omitted */ }

A handle to the standard input stream of a process.

Each handle is a shared reference to a global buffer of input data to this process. A handle can be lock'd to gain full access to BufRead methods (e.g. .lines()). Reads to this handle are otherwise locked with respect to other reads.

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

Created by the io::stdin method.

Methods

impl Stdin

pub fn lock(&self) -> StdinLock

Locks this handle to the standard input stream, returning a readable guard.

The lock is released when the returned lock goes out of scope. The returned guard also implements the Read and BufRead traits for accessing the underlying data.

pub fn read_line(&self, buf: &mut String) -> Result<usize>

Locks this handle and reads a line of input into the specified buffer.

For detailed semantics of this method, see the documentation on BufRead::read_line.

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

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize>

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self where     Self: Sized,

Creates a "by reference" adaptor for this instance of Read.

Important traits for Bytes<R>

impl<R: Read> Iterator for Bytes<R> type Item = Result<u8>;

fn bytes(self) -> Bytes<Self> where     Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

Important traits for Chars<R>

impl<R: Read> Iterator for Chars<R> type Item = Result<char, CharsError>;

fn chars(self) -> Chars<Self> where     Self: Sized,

Transforms this Read instance to an Iterator over chars.

fn chain<R: Read>(self, next: R) -> Chain<Self, R> where     Self: Sized,

Creates an adaptor which will chain this stream with another.

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

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

impl AsRawFd for Stdin

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.
