Struct Block 

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

A widget that draws a block with optional borders, title, and padding.

Implementations

impl<'a> Block<'a>

pub fn new() -> Self

Create a new block with default settings.

pub fn bordered() -> Self

Create a block with all borders enabled and default padding.

pub fn borders(self, borders: Borders) -> Self

Set which borders to render.

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

Set the style applied to border characters.

pub fn border_type(self, border_type: BorderType) -> Self

Set the border character set (e.g. square, rounded, double).

pub fn padding(self, padding: impl Into<Sides>) -> Self

Set the padding inside the borders.

pub fn title(self, title: &'a str) -> Self

Set the block title displayed on the top border.

pub fn title_alignment(self, alignment: Alignment) -> Self

Set the horizontal alignment of the title.

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

Set the background style for the entire block area.

pub fn inner(&self, area: Rect) -> Rect

Compute the inner area inside the block’s borders and padding.

pub fn chrome_size(&self) -> (u16, u16)

Calculate the chrome (border + padding) size consumed by this block.

Returns (horizontal_chrome, vertical_chrome) representing the total width and height consumed by borders and padding.

Trait Implementations

impl<'a> Clone for Block<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Block<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Block<'a>

fn default() -> Block<'a>

Returns the “default value” for a type.

impl MeasurableWidget for Block<'_>

fn measure(&self, _available: Size) -> SizeConstraints

Measure the widget given available space.

fn has_intrinsic_size(&self) -> bool

Quick check: does this widget have content-dependent sizing?

impl<'a> PartialEq for Block<'a>

fn eq(&self, other: &Block<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Widget for Block<'_>

fn render(&self, area: Rect, frame: &mut Frame<'_>)

Render the widget into the frame at the given area.

fn is_essential(&self) -> bool

Whether this widget is essential and should always render.
