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.

Trait Implementations

impl Clone for DynamicNode

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicNode

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

Formats the struct fields as a debug struct, skipping excluded fields.

Arguments

• &mut std::fmt::Formatter<'_> - The formatter to write the representation into.

Returns

• std::fmt::Result - Success or failure of the formatting operation.

impl Default for DynamicNode

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

fn default() -> Self

Constructs a default DynamicNode value.
