Struct Layout 

pub struct Layout { /* private fields */ }

Defines a horizontal and vertical grid layout setup.

Layout is used for separating a given total space (e.g., the window size) into easy-to-manage rectangular chunks for rendering UI elements.

Implementations

impl Layout

pub fn new() -> Self

Starts a new Layout definition.

pub fn row( self, height_constraint: Constraint, width_constraints: Vec<Constraint>, ) -> Self

Adds a new row to the layout with specified height and column width constraints.

pub fn empty_row(self, constraint: Constraint) -> Self

Creates a row that takes up the full width of the available space with a single height constraint.

pub fn calculate( self, space: impl Into<Vec2>, ) -> Result<Vec<Vec<Rect>>, LayoutError>

Calculates the Rects for all elements in the layout based on the total available space.

pub fn render<R: Render>( self, space: impl Into<Vec2>, buffer: &mut Buffer, elements: Vec<Vec<R>>, ) -> Result<Vec<Vec<Rect>>, LayoutError>

Calculates the layout and renders elements to each rect area.

pub fn render_clipped<R: Render>( self, space: impl Into<Vec2>, buffer: &mut Buffer, elements: Vec<Vec<R>>, ) -> Result<Vec<Vec<Rect>>, LayoutError>

Calculates the layout and renders elements with clipping to fit within each rect.

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Layout

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

Formats the value using the given formatter.

impl Default for Layout

fn default() -> Layout

Returns the “default value” for a type.
