Struct Node 

pub struct Node {
    pub id: String,
    pub topic: String,
    pub children: Vec<Node>,
    pub expanded: bool,
    pub direction: Option<NodeDirection>,
    pub style: Option<NodeStyle>,
    pub branch_color: Option<String>,
    pub note: Option<String>,
    pub image: Option<NodeImage>,
    pub metadata: Option<Value>,
}

A plain-text node in the persistent nested tree.

Fields

id: String

Stable ID, unique within this document.

topic: String

Plain-text label, including optional line breaks.

children: Vec<Node>

Ordered children.

expanded: bool

Whether children are visible; missing means expanded.

direction: Option<NodeDirection>

Side assigned to a main branch.

style: Option<NodeStyle>

Explicit per-node appearance.

branch_color: Option<String>

Explicit branch stroke, inherited by descendants.

note: Option<String>

Plain-text note; not rendered on the canvas (hosts show it in details).

image: Option<NodeImage>

Optional picture rendered above the topic.

metadata: Option<Value>

Opaque JSON metadata, including explicit null, preserved without interpretation.
