Enum re_view_graph::ui::state::LayoutState

pub enum LayoutState {
    None,
    InProgress {
        layout: Layout,
        provider: ForceLayoutProvider,
        params: ForceLayoutParams,

}

The following is a simple state machine that keeps track of the different layouts and if they need to be recomputed. It also holds the state of the force-based simulation.

Implementations

impl LayoutState

pub fn bounding_rect(&self) -> Option<Rect>

pub fn reset(&mut self)

pub fn is_none(&self) -> bool

pub fn is_in_progress(&self) -> bool

fn update( self, new_request: LayoutRequest, new_params: ForceLayoutParams, ) -> Self

A simple state machine that keeps track of the different stages and if the layout needs to be recomputed.

pub fn get( &mut self, request: LayoutRequest, params: ForceLayoutParams, ) -> &mut Layout

This method is lazy. A new layout is only computed if the current timestamp requires it.

Trait Implementations

impl Default for LayoutState

fn default() -> LayoutState

Returns the “default value” for a type.
