Struct DynamicNode 

pub struct DynamicNode { /* private fields */ }

A closure-based dynamic node that re-renders when its dependency signals change.

Holds a shared reference to a heap-allocated render closure that produces a fresh VirtualNode on each evaluation. The renderer subscribes to the closure’s signals and patches the DOM automatically. Contains a HookContext that persists hook state (like use_signal) across re-renders, ensuring that signal values are not reset when the render function is called again.

Uses Rc<UnsafeCell<>> instead of Rc<RefCell<>> to avoid runtime borrow checking overhead. Safety is guaranteed by the single-threaded WASM context. The Rc provides automatic memory management — the render closure is freed when the last reference (either in the VirtualNode tree or the signal update callback) is dropped.

Implementations

impl DynamicNode

Implementation of dynamic node accessor methods.

pub fn render(&self) -> VirtualNode

Invokes the render closure and returns the produced virtual node.

Safety

Must only be called from the main thread. Guaranteed in WASM single-threaded context. No concurrent access is possible.

Returns

• VirtualNode - The virtual node produced by the render closure.

impl DynamicNode

pub fn new( render_fn: Rc<UnsafeCell<RenderFnInner>>, hook_context: HookContext, ) -> Self

Performs copy-assignment from source.

impl Debug for DynamicNode

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

impl Default for DynamicNode

Provides a default empty dynamic node with a no-op render function.

fn default() -> Self
