Struct ValueBar 

pub struct ValueBar<'a> { /* private fields */ }

A symmetrical gauge for a value

Implementations

impl<'a> ValueBar<'a>

pub fn value(self, value: f32) -> Self

Set the value how much this bar should be filled. Should be between [-range..range]

pub fn range(self, range: f32) -> Self

The upper and lower bound of the gauge.

pub fn label<T>(self, label: T) -> Self

where T: Into<Cow<'a, str>>,

Show a label at the zero position of the bar. By default no label is shown. If width of bar is too small, the label won’t be rendered.

pub fn direction(self, direction: Direction) -> Self

Set that this bar is filling horizontally (default) or vertically

pub fn block(self, block: Block<'a>) -> Self

Surround this bar by a Block

pub fn style(self, style: Style) -> Self

Apply a custom style to this bar

Trait Implementations

impl<'a> Clone for ValueBar<'a>

fn clone(&self) -> ValueBar<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ValueBar<'a>

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

Formats the value using the given formatter.

impl<'a> Default for ValueBar<'a>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Widget for ValueBar<'a>

fn render(self, area: Rect, buffer: &mut Buffer)

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom widget.
