Struct HookContext 

pub struct HookContext { /* private fields */ }

Manages hook state across render cycles for a DynamicNode.

Stores boxed Any values keyed by hook call order, enabling use_signal and similar hooks to persist state between re-renders of the same dynamic node.

Implements Clone for ergonomic use; all clones share the same underlying state.

Implementations

impl HookContext

Implementation of hook context lifecycle and hook index management.

pub fn reset_hook_index(&mut self)

Resets the hook index for a new render cycle.

Sets the internal hook index back to zero so that subsequent use_signal calls start indexing from the beginning of the hook list.

pub fn set_arm_changed(&mut self, changed: usize)

Notifies the hook context that a match arm is being entered.

If the arm index has changed, all existing hooks and cleanups are cleared and re-initialized for the new arm. If the arm is unchanged, only the hook index is reset.

Arguments

• usize: The index of the new match arm.

impl HookContext

pub fn get_mut_inner(&mut self) -> &mut Rc<RefCell<HookContextInner>>

impl HookContext

pub fn new(inner: Rc<RefCell<HookContextInner>>) -> Self

Trait Implementations

impl Clone for HookContext

Clones the hook context, sharing the same inner state.

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 HookContext

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

Formats the value using the given formatter.

impl Default for HookContext

Provides a default empty hook context.

fn default() -> Self

Returns the “default value” for a type.
