Struct InstanceNode 

pub struct InstanceNode {
    pub id: String,
    pub name: Option<String>,
    pub role: Option<String>,
    pub component: String,
    pub x: Option<Dimension>,
    pub y: Option<Dimension>,
    pub opacity: Option<f64>,
    pub visible: Option<bool>,
    pub locked: Option<bool>,
    pub overrides: Vec<Override>,
    pub source_span: Option<Span>,
    pub unknown_props: BTreeMap<String, UnknownProperty>,
}

An instance node — a placement of a declared ComponentDef at an origin (x, y), with an optional opacity/visible cascade and instance-local overrides.

At compile time the instance expands to the component’s child subtree treated as a GROUP translated by (x, y), cascading opacity/visible exactly like a GroupNode. Every expanded descendant id is PREFIXED with the instance id (<instance-id>/<local-id>) so multiple instances of the same component never collide. The instance node itself emits no scene command; its expanded subtree does. Expansion happens at COMPILE time only — the instance stays a single node in the canonical AST so parse→format→parse round-trips.

Fields

id: String

name: Option<String>

role: Option<String>

component: String

The referenced ComponentDef id.

x: Option<Dimension>

Instance origin x-translation applied to the expanded subtree (default 0).

y: Option<Dimension>

Instance origin y-translation applied to the expanded subtree (default 0).

opacity: Option<f64>

Opacity that cascades (multiplies) into all expanded descendant alphas.

visible: Option<bool>

When Some(false) the entire expanded subtree is excluded from the render.

locked: Option<bool>

overrides: Vec<Override>

Instance-local overrides applied to component descendants on expansion.

source_span: Option<Span>

Source declaration span, when available.

unknown_props: BTreeMap<String, UnknownProperty>

Unknown properties preserved for forward-compat.

Trait Implementations

impl Clone for InstanceNode

fn clone(&self) -> InstanceNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InstanceNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for InstanceNode

fn eq(&self, other: &InstanceNode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
