Struct Stdin 

pub struct Stdin { /* private fields */ }

A handle to the standard input stream of a process.

Implementations

impl Stdin

pub fn lock(&self) -> StdinLock<'static>

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>

Available on crate feature alloc only.

Locks this handle and reads a line of input, appending it to the specified buffer.

Trait Implementations

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.

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

Read the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_, u8>) -> Result<(), IoError>

Pull some bytes from this source into the specified buffer.

fn read_buf_exact( &mut self, cursor: BorrowedCursor<'_, u8>, ) -> Result<(), IoError>

Reads the exact number of bytes required to fill cursor.

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

Available on crate feature alloc only.

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

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

Available on crate feature alloc only.

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

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Read.

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

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

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

where Self: Sized,

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