Struct termfest::ScreenLock

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

ScreenLock is a locked screen buffer, created by Termfest::lock_screen. When it is dropped, the buffered state will be flushed to the terminal. All rendering manipulation is implemented in ScreenLock.

Methods

impl<'a> ScreenLock<'a>

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

flushes the internal buffer states to the terminal. Even if this function is not called, the buffer will be flushed when self is dropped.

fn clear(&mut self)

clear the internal buffer states. If clear and flush is called, the terminal will be cleared (nothing will be rendered).

fn move_cursor(&mut self, x: usize, y: usize)

fn hide_cursor(&mut self)

fn show_cursor(&mut self)

fn print(&mut self, x: usize, y: usize, s: &str, attr: Attribute)

print string with the given attribute. It is equal to put_cell calls with each character.

fn put_cell(&mut self, x: usize, y: usize, cell: Cell)

fn size(&self) -> (usize, usize)

returns the width and height of the terminal.

Trait Implementations

impl<'a> Drop for ScreenLock<'a>

fn drop(&mut self)

Executes the destructor for this type.
