Struct NodesState

Source 
pub struct NodesState<Key: NodeKey> { /* private fields */ }
Expand description

NodesState stores the nodes states given incoming events.

Implementations§

Source§

impl<Key: NodeKey> NodesState<Key>

Source

pub fn create_update<Emmitable: EmmitableEvent<Key = Key, Name = Name>, Name: NameOfEvent, Source: SourceEvent>( &self, events_measurer: &impl EventsMeasurer<Key = Key, Name = Name>, potential_events: &PotentialEvents<Key, Name, Source>, ) -> NodesStatesUpdate<Key>

Create the nodes states given the PotentialEvents.

Source

pub fn apply_update(&mut self, update: NodesStatesUpdate<Key>)

Apply the given NodesStatesUpdate in a way so that only newly hovered/pressed nodes are cached. Any discard of nodes in the NodesStatesUpdate wont matter here.

Source

pub fn is_hovered(&self, key: Key) -> bool

Source

pub fn is_pressed(&self, key: Key) -> bool
