Struct TreeNode 

pub struct TreeNode {
    pub id: String,
    pub type_name: String,
    pub props: Value,
    pub children: Vec<TreeNode>,
}

A single node in the UI tree.

Each node has a unique id (scoped to the tree, assigned by the host), a type_name that determines which widget renders it, a props map of widget-specific properties, and optional children for container widgets.

Extension authors receive &TreeNode in their render method.

Fields

id: String

Unique identifier for this node within the tree.

type_name: String

Widget type name (e.g. "button", "text", "slider"). Determines which renderer handles this node.

props: Value

Widget-specific properties. Always a JSON object (defaults to {} when omitted). Individual widgets read their props via helpers like prop_str.

children: Vec<TreeNode>

Child nodes for container widgets. Empty for leaf widgets.

Trait Implementations

impl Clone for TreeNode

fn clone(&self) -> TreeNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreeNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TreeNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TreeNode

fn eq(&self, other: &TreeNode) -> 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.

impl Serialize for TreeNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
