Struct termion::screen::AlternateScreen

pub struct AlternateScreen<W: Write> { /* fields omitted */ }

A terminal restorer, which wraps a type implementing Write, and causes all writes to be written to an alternate screen.

This is achieved by switching the terminal to the alternate screen on creation and automatically switching it back to the original screen on drop.

Methods

impl<W: Write> AlternateScreen<W>

pub fn from(output: W) -> Self

Create an alternate screen wrapper struct for the provided output and switch the terminal to the alternate screen.

Trait Implementations

impl<W: Write> Drop for AlternateScreen<W>

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write> DerefMut for AlternateScreen<W>

fn deref_mut(&mut self) -> &mut W

Mutably dereferences the value.

impl<W: Write> Deref for AlternateScreen<W>

type Target = W

The resulting type after dereferencing.

fn deref(&self) -> &W

Dereferences the value.

impl<W: Write> Write for AlternateScreen<W>

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.
