Struct NodeState 

pub struct NodeState { /* private fields */ }

Runtime state tracked for every ModifierNode.

This type is part of the internal node system API and should not be directly constructed or manipulated by external code. Modifier nodes automatically receive and manage their NodeState through the modifier chain infrastructure.

Implementations

impl NodeState

pub const fn new() -> NodeState

Creates the state of a node that is not attached to a chain yet and has no capabilities.

pub fn set_capabilities(&self, capabilities: NodeCapabilities)

Records the capabilities of the node that owns this state. The chain calls it when it adds or updates the node.

pub fn capabilities(&self) -> NodeCapabilities

The capabilities of the node that owns this state.

pub fn is_attached(&self) -> bool

Whether the node is attached to a chain. It is true after on_attach ran and before on_detach runs.

impl Default for NodeState

fn default() -> NodeState
