Struct TerminalGuard 

pub struct TerminalGuard<B: Backend + Write> {
    pub(crate) terminal: Terminal<B>,
    pub(crate) hook: Option<Arc<Box<dyn Fn(&PanicHookInfo<'_>) + Sync + Send + 'static>>>,
}

Handles terminal setup and teardown for interactive TUIs.

Fields

terminal: Terminal<B>

hook: Option<Arc<Box<dyn Fn(&PanicHookInfo<'_>) + Sync + Send + 'static>>>

Implementations

impl<B: Backend + Write> TerminalGuard<B>

pub fn with<T>(terminal: Terminal<B>, f: impl FnMut(&mut Terminal<B>) -> T) -> T

Runs a closure while the terminal is in alternate-screen raw mode.

pub(crate) fn setup(&mut self)

pub(crate) fn restore(&mut self)

pub(crate) fn half_restore(w: &mut impl Write)

Trait Implementations

impl<B: Backend + Write> Drop for TerminalGuard<B>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
