Struct LayerKey 

pub struct LayerKey {
    pub element_id: u64,
    pub revision: u64,
}

Identifies a cached layer by element and content revision.

Runtime bumps revision on the element and all ancestors whenever a repaint-relevant dirty flag or direct damage mark reaches the subtree.

Fields

element_id: u64

revision: u64
