Struct vt::Vt

pub struct Vt<'a> { /* fields omitted */ }

An allocated virtual terminal.

Methods

impl<'a> Vt<'a>

pub fn number(&self) -> u16

Returns the number of this virtual terminal.

pub fn switch(&self) -> Result<&Self>

Switches to this virtual terminal. This is just a shortcut for Console::switch_to.

Returns self for chaining.

pub fn clear(&mut self) -> Result<&mut Self>

Clears the terminal.

Returns self for chaining.

pub fn set_blank_timer(&mut self, timer: u32) -> Result<&mut Self>

Sets the blank timer for this terminal. A value of 0 disables the timer.

Returns self for chaining.

pub fn blank(&mut self, blank: bool) -> Result<&mut Self>

Blanks or unlanks the terminal.

Returns self for chaining.

pub fn echo(&mut self, echo: bool) -> Result<&mut Self>

Enables or disables the echo of the characters typed by the user.

Returns self for chaining.

pub fn get_echo(&mut self) -> Result<bool>

Returns a value indicating whether this terminal has echo enabled or not.

pub fn signals(&mut self, signals: VtSignals) -> Result<&mut Self>

Enables or disables signal generation from terminal.

Returns self for chaining.

pub fn flush_buffers(&mut self, t: VtFlushType) -> Result<&mut Self>

Flushes the internal buffers of the terminal.

Trait Implementations

impl<'a> Drop for Vt<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> Write for Vt<'a>

Writing to a Vt writes directly to the underlying terminal.

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

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

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

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

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

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

impl<'a> Read for Vt<'a>

Reading from a Vt reads directly from the underlying terminal.

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_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

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 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.
