Expand description

Public trait exposed to measure policies for subcomposition.

Required Methods§

Source

fn subcompose<Content>( &mut self, slot_id: SlotId, content: Content, ) -> Vec<SubcomposeChild>
where Content: FnOnce(),

Source

fn measure( &mut self, child: SubcomposeChild, constraints: Constraints, ) -> SubcomposePlaceable

Measures a subcomposed child with the given constraints.

Source

fn node_has_no_parent(&self, node_id: NodeId) -> bool

Checks if a node has no parent (is a root node). Used to filter subcompose results to only include true root nodes.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
