Struct ContainerCtx 

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

Closure context passed into row() / col() closures for accumulating children.

Each method adds a child node (panel, nested container, or grid) to the parent being built. Errors are deferred: the first failure is stored and all subsequent operations become no-ops. The stored error surfaces when the parent builder method returns.

Implementations

impl ContainerCtx<'_>

pub fn add(&mut self, pid: PanelId)

Place a pre-created panel (from LayoutBuilder::panel) into this container.

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

Add a panel child with grow(1.0) default constraints. Returns its PanelId.

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

Add a panel child with explicit constraints. Returns its PanelId.

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

Nest a row container with zero gap. Children are built in the closure.

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

Nest a row container with the specified gap between children.

pub fn row_with( &mut self, constraints: Constraints, f: impl FnOnce(&mut ContainerCtx<'_>), )

Nest a row container with explicit constraints and zero gap.

pub fn row_gap_with( &mut self, gap: f32, constraints: Constraints, f: impl FnOnce(&mut ContainerCtx<'_>), )

Nest a row container with explicit constraints and the specified gap.

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

Nest a column container with zero gap. Children are built in the closure.

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

Nest a column container with the specified gap between children.

pub fn col_with( &mut self, constraints: Constraints, f: impl FnOnce(&mut ContainerCtx<'_>), )

Nest a column container with explicit constraints and zero gap.

pub fn col_gap_with( &mut self, gap: f32, constraints: Constraints, f: impl FnOnce(&mut ContainerCtx<'_>), )

Nest a column container with explicit constraints and the specified gap.

pub fn grid(&mut self, grid: Grid, f: impl FnOnce(&mut GridCtx<'_>))

Nest a grid container. Grid items are built in the closure via GridCtx.

pub fn taffy_node( &mut self, style: Style, f: impl FnOnce(&mut ContainerCtx<'_>), )

Insert a raw Taffy node with a custom style. Escape hatch for layouts that cannot be expressed through row/col/grid primitives.
