Struct LayoutBuilder 

pub struct LayoutBuilder { /* private fields */ }

Ergonomic builder for constructing layouts.

Users create panels, arrange them in row()/col() containers via closures, then call build() to get a Layout ready for resolution.

Implementations

impl LayoutBuilder

pub fn new() -> Self

Create an empty builder with no root set.

pub fn panel(&mut self, kind: impl Into<Arc<str>>) -> Result<PanelId, PaneError>

Create a panel with grow(1.0) default constraints.

pub fn panel_with( &mut self, kind: impl Into<Arc<str>>, constraints: Constraints, ) -> Result<PanelId, PaneError>

Create a panel with explicit constraints.

pub fn row( &mut self, f: impl FnOnce(&mut ContainerCtx<'_>), ) -> Result<(), PaneError>

Set the root to a row container with zero gap.

pub fn row_gap( &mut self, gap: f32, f: impl FnOnce(&mut ContainerCtx<'_>), ) -> Result<(), PaneError>

Set the root to a row container with the specified gap.

pub fn col( &mut self, f: impl FnOnce(&mut ContainerCtx<'_>), ) -> Result<(), PaneError>

Set the root to a column container with zero gap.

pub fn col_gap( &mut self, gap: f32, f: impl FnOnce(&mut ContainerCtx<'_>), ) -> Result<(), PaneError>

Set the root to a column container with the specified gap.

pub fn set_window_size(&mut self, size: usize)

Consume the builder, validate the tree, and return a Layout. Set how many panels the active window shows at once.

pub fn build(self) -> Result<Layout, PaneError>

Validate the tree and produce a Layout.

Trait Implementations

impl Default for LayoutBuilder

fn default() -> Self

Returns the “default value” for a type.
