Trait CacheTree 

pub trait CacheTree {
    // Required methods
    fn cache_get(
        &self,
        node_id: NodeId,
        known_dimensions: Size<Option<f32>>,
        available_space: Size<AvailableSpace>,
        run_mode: RunMode,
    ) -> Option<LayoutOutput>;
    fn cache_store(
        &mut self,
        node_id: NodeId,
        known_dimensions: Size<Option<f32>>,
        available_space: Size<AvailableSpace>,
        run_mode: RunMode,
        layout_output: LayoutOutput,
    );
    fn cache_clear(&mut self, node_id: NodeId);
}

Trait used by the compute_cached_layout method which allows cached layout results to be stored and retrieved.

The Cache struct implements a per-node cache that is compatible with this trait.

Required Methods

fn cache_get( &self, node_id: NodeId, known_dimensions: Size<Option<f32>>, available_space: Size<AvailableSpace>, run_mode: RunMode, ) -> Option<LayoutOutput>

Try to retrieve a cached result from the cache

fn cache_store( &mut self, node_id: NodeId, known_dimensions: Size<Option<f32>>, available_space: Size<AvailableSpace>, run_mode: RunMode, layout_output: LayoutOutput, )

Store a computed size in the cache

fn cache_clear(&mut self, node_id: NodeId)

Clear all cache entries for the node
