Struct ClipperBuffer 

pub struct ClipperBuffer<'a, W>
where
    W: Eq + Clone + Hash,
{ /* private fields */ }

Second stage: render widgets to the temporary buffer.

Implementations

impl<'a, W> ClipperBuffer<'a, W>

where W: Eq + Hash + Clone,

pub fn is_visible(&self, widget: W) -> bool

Is the widget visible.

pub fn render_label<FN>(&mut self, widget: W, render_fn: FN) -> bool

where FN: FnOnce(&Option<Cow<'static, str>>, Rect, &mut Buffer),

Render the label for the given widget.

pub fn render_widget<FN, WW>(&mut self, widget: W, render_fn: FN) -> bool

where FN: FnOnce() -> WW, WW: Widget,

Render a stateless widget and its label.

pub fn render<FN, WW, SS>( &mut self, widget: W, render_fn: FN, state: &mut SS, ) -> bool

where FN: FnOnce() -> WW, WW: StatefulWidget<State = SS>, SS: RelocatableState,

Render a stateful widget and its label.

pub fn locate_widget(&self, widget: W) -> Option<Rect>

Get the buffer coordinates for the given widget.

pub fn locate_label(&self, widget: W) -> Option<Rect>

Get the buffer coordinates for the label of the given widget.

pub fn locate_area(&self, area: Rect) -> Option<Rect>

Relocate the area from layout coordinates to buffer coordinates, which is a noop as those are aligned.

But this will return None if the given area is outside the buffer.

pub fn buffer(&mut self) -> &mut Buffer

Return a reference to the buffer.

pub fn finish(self, buffer: &mut Buffer, state: &mut ClipperState<W>)

Trait Implementations

impl<'a, W> Debug for ClipperBuffer<'a, W>

where W: Eq + Clone + Hash + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, W> Drop for ClipperBuffer<'a, W>

where W: Eq + Hash + Clone,

fn drop(&mut self)

Executes the destructor for this type.
