Struct RenderContext 

pub struct RenderContext {
    pub fiber_tree: FiberTree,
    pub state_batch: StateBatch,
    pub effect_queue: EffectQueue,
    pub context_stack: ContextStack,
    pub event_state: EventState,
}

Consolidated render context containing all render-related state.

This struct combines all the previously separate thread-local state into a single location for easier management and better encapsulation.

Fields

fiber_tree: FiberTree

Fiber tree tracking all mounted component instances

state_batch: StateBatch

State batch for grouping multiple state updates

effect_queue: EffectQueue

Effect queue for post-commit effect execution

context_stack: ContextStack

Context stack for React-like context system

event_state: EventState

Current event state for terminal event handling

Implementations

impl RenderContext

pub fn new() -> Self

Create a new render context with default state

pub fn prepare_for_render(&mut self)

Reset all state for a new render pass

This prepares the context for a new frame by:

• Resetting hook indices in the fiber tree
• Clearing the current event

pub fn set_event(&mut self, event: Option<Arc<Event>>)

Set the current event for this render pass

pub fn clear_event(&mut self)

Clear the current event

pub fn begin_batch(&mut self)

Begin state batching

pub fn end_batch(&mut self) -> HashSet<FiberId>

End state batching and apply updates

Returns the set of fiber IDs that were modified

pub fn flush_effects(&mut self)

Flush synchronous effects

pub async fn flush_async_effects(&mut self)

Flush async effects

pub fn mark_unseen_for_unmount(&mut self)

Mark unseen fibers for unmount

pub fn process_unmounts(&mut self) -> Vec<FiberId>

Process pending unmounts

This cleans up context values and removes fibers that were scheduled for unmount.

pub fn clear(&mut self)

Clear all state

This resets the context to its initial state, useful for cleanup at the end of the render loop or in tests.

Trait Implementations

impl Default for RenderContext

fn default() -> Self

Returns the “default value” for a type.
