Struct axstd::io::Stdin

source ·
pub struct Stdin { /* private fields */ }
Expand description

A handle to the standard input stream of a process.

Implementations§

source§

impl Stdin

source

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.

source

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§

source§

impl Read for Stdin

source§

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.
source§

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

Available on crate feature alloc only.
Read all bytes until EOF in this source, placing them into buf.
source§

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

Available on crate feature alloc only.
Read all bytes until EOF in this source, appending them to buf.
source§

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

Read the exact number of bytes required to fill buf.
source§

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

Read the exact number of bytes required to fill buf.
