Module runtime 

The runtime in which a composition runs: state cells, UI tasks, frame callbacks and the queue of invalidated scopes.

Structs

DefaultScheduler

A scheduler that ignores frame requests, for compositions that the caller drives itself.

Runtime

Owns the state cells, UI tasks, frame callbacks and invalidated scopes of one composition. Clones share the same runtime.

RuntimeDebugStats

Sizes of a runtime’s queues and tables, for leak and memory checks. A _len field counts entries and a _cap field the capacity reserved.

RuntimeHandle

A cheap handle to a Runtime. It does not keep the runtime alive, and its calls do nothing once the runtime is dropped.

RuntimeId

Identifies a runtime within its thread.

RuntimeThreadLocalDebugStats

Sizes of the runtime registries of one thread, for leak and memory checks. A _len field counts entries and a _cap field the capacity reserved.

StateArenaDebugStats

Sizes of a runtime’s state arena, for leak and memory checks. A _len field counts entries and a _cap field the capacity reserved.

StateId

Names one state cell of a runtime. A generation count makes the id of a freed cell stale.

TaskHandle

Controls a future spawned with RuntimeHandle::spawn_ui.

UiDispatcher

Posts work from any thread to the UI thread of a runtime.

Functions

current_runtime_handle

Gets the current runtime handle from thread-local storage.

debug_runtime_thread_local_stats

Returns the sizes of the runtime registries of the current thread, for leak and memory checks.

label_next_ui_task

Names the next task that spawn_ui creates on this thread, for live_ui_task_labels and leak reports. A task with no label is called unnamed.

schedule_frame

Schedule a new frame render using the most recently active runtime handle.

schedule_node_update

Schedule an in-place node update using the most recently active runtime.
