Struct DepGraphView 

pub struct DepGraphView {
    pub title: String,
    pub nodes: Vec<DepNode>,
    pub edges: Vec<DepEdge>,
    pub selected: Option<usize>,
}

The layered dep-graph viewer. Implements Facet.

Fields

title: String

nodes: Vec<DepNode>

edges: Vec<DepEdge>

selected: Option<usize>

Implementations

impl DepGraphView

pub fn new(nodes: Vec<DepNode>, edges: Vec<DepEdge>) -> Self

pub fn with_title(self, t: impl Into<String>) -> Self

pub fn columns(&self) -> Vec<usize>

Column index per node — toposort, deps first (left). Longest-path layering so a dependent sits right of all its deps. Cycle → best effort.

pub fn show(&mut self, ui: &mut Ui)

Trait Implementations

impl Facet for DepGraphView

fn caps(&self) -> FacetCaps

Boxes/arrows/labels are painted from the active [Theme]; a node can be click-selected (drives the drill-down panel); the layered canvas takes the host’s available_size.

fn title(&self) -> &str

fn ui(&mut self, ui: &mut Ui)

fn state_json(&self) -> Value

fn selection_json(&self) -> Value

The current selection as JSON (also folded into state_json by convention). Null when nothing/none selectable.

fn scale(&self) -> f32

Current uniform scale (1.0 = native). Override if caps().scalable.

fn set_scale(&mut self, _scale: f32)

Set the uniform scale; clamp internally. Default no-op (not scalable).

fn copy(&mut self) -> Option<String>

Clipboard hooks — see clipboard.rs. Defaults: nothing to give/take. Returns the text to place on the clipboard (None = nothing copyable now).

fn cut(&mut self) -> Option<String>

Like copy, but also removes the selection. Default delegates to copy.

fn paste(&mut self, _text: &str) -> bool

Accept pasted text. Returns true if consumed.

fn as_any_mut(&mut self) -> Option<&mut (dyn Any + 'static)>

Optional downcast handle for hosts that need typed access to a specific facet living inside a FacetDeck (e.g. a robot-UI driver clicking an app-level control that must forward to a concrete component’s own API). Defaulted to None so no existing facet has to change; a component opts in by returning Some(self).
