Modules

collections

composer_context

hash

owned

platform

Platform abstraction traits for Compose runtime services.

runtime

slot_table

Slot table implementation with a single logical gap buffer and explicit hidden entries.

snapshot_double_index_heap

snapshot_id_set

snapshot_pinning

snapshot_state_observer

snapshot_v2

Snapshot system for managing isolated state changes.

subcompose

State tracking for measure-time subcomposition.

Macros

DisposableEffect

LaunchedEffect

LaunchedEffectAsync

clone_captures

Structs

AnchorId

Stable identifier for a slot in the slot table.

ApplierGuard

CallbackHolder

CallbackHolder1

CallbackHolder1 keeps the latest single-argument callback closure alive across recompositions. It mirrors CallbackHolder but supports callbacks that receive one argument.

CancelToken

Cooperative cancellation token passed into background LaunchedEffect work.

Composer

Composition

CompositionLocal

CompositionPassDebugStats

ConcreteApplierHost

DisposableEffectResult

DisposableEffectScope

GroupId

Opaque handle to a group in the slot storage.

LaunchedEffectScope

MemoryApplier

MemoryApplierDebugStats

MutableState

Cheap copyable mutable view of a state cell.

OwnedMutableState

Owning state handle for reclaimable state cells.

ParamSlot

ParamSlot holds function/closure parameters by ownership (no PartialEq/Clone required). Used by the #[composable] macro to store Fn-like parameters in the slot table.

ParamState

ProvidedValue

RecomposeOptions

RecomposeScope

RecomposeScopeRegistryDebugStats

RecycledNode

ReturnSlot

SlotsHost

SnapshotStateList

SnapshotStateMap

StartScopedGroup

Result of starting a scoped group.

State

Cheap copyable read-only view of a state cell.

StaticCompositionLocal

A StaticCompositionLocal is a CompositionLocal that is optimized for values that are unlikely to change. Unlike CompositionLocal, reads of a StaticCompositionLocal are not tracked by the recomposition system, which means:

ValueSlotHandle

Enums

NodeError

Phase

Constants

ROOT_RENDER_REPLAY_LIMIT

Upper bound on chained root-render replays and scope-recomposition rounds.

bubble_layout_dirty

Unified API for bubbling layout dirty flags from a node to the root (Applier context).

bubble_layout_dirty_in_composer

Unified API for bubbling layout dirty flags from a node to the root (Composer context).

bubble_measure_dirty

Unified API for bubbling measure dirty flags from a node to the root (Applier context).

bubble_measure_dirty_in_composer

Unified API for bubbling measure dirty flags from a node to the root during composition.

bubble_semantics_dirty

Unified API for bubbling semantics dirty flags from a node to the root (Applier context).

bubble_semantics_dirty_in_composer

Unified API for bubbling semantics dirty flags from a node to the root (Composer context).

compositionLocalOf

compositionLocalOfWithPolicy

derivedStateOf

dispatch_ui_event

Dispatches a UI event in a proper snapshot context.

enter_event_handler

Marks the start of an event handler context. Call this at the start of keyboard/mouse/touch event handling. Use run_in_mutable_snapshot or dispatch_ui_event inside to ensure proper snapshot handling.

exit_event_handler

Marks the end of an event handler context.

in_applied_snapshot

Returns true if currently in an applied snapshot context.

in_event_handler

Returns true if currently in an event handler context.

location_key

mutableStateList

mutableStateListOf

mutableStateMap

mutableStateMapOf

mutableStateOf

Creates a new MutableState initialized with the given value.

ownedMutableStateOf

pop_parent

push_parent

queue_semantics_invalidation

Schedules semantics bubbling for a node using the active composer if present.

remember

rememberUpdatedState

Returns a MutableState that always holds the latest value.

run_in_mutable_snapshot

Runs the provided closure inside a mutable snapshot and applies the result.

staticCompositionLocalOf

try_mutableStateOf

Like mutableStateOf but returns None if no runtime is available.

useState

A composable hook that creates and remembers a MutableState.
