Struct SystemChart 

pub struct SystemChart {
    pub title: String,
    pub nodes: Vec<SysNode>,
    pub edges: Vec<SysEdge>,
    /* private fields */
}

The system-map chart: nodes + edges + the current selection.

Fields

title: String

nodes: Vec<SysNode>

edges: Vec<SysEdge>

Implementations

impl SystemChart

pub fn new( title: impl Into<String>, nodes: Vec<SysNode>, edges: Vec<SysEdge>, ) -> Self

pub fn with_canvas_height(self, h: f32) -> Self

pub fn select(&mut self, id: &str)

Select a node by id (headless-test + host entry point). Selecting the already-selected node deselects it. Unknown id is a no-op.

pub fn clear_selection(&mut self)

Clear the selection.

pub fn selected(&self) -> Option<&str>

The selected node’s id, if any.

pub fn set_badge(&mut self, id: &str, badge: u64)

Update a node’s badge by id (e.g. a live event count). No-op if unknown.

pub fn set_detail(&mut self, id: &str, detail: impl Into<String>)

Update a node’s detail text by id. No-op if unknown.

Trait Implementations

impl Facet for SystemChart

fn caps(&self) -> FacetCaps

Painted with the active Theme (nodes/edges/text/accent ring), and its canvas takes the host’s available width — themeable + resizable.

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

Opt into typed downcast so a host (e.g. the demo’s robot-UI node-select toolbar) can forward a selection to SystemChart::select when this chart lives boxed inside a FacetDeck.

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.
