Function: reducePlayerState()

function reducePlayerState(
   state: PlayerState, 
   event: PlayerEvent, 
   context: ReducerContext
): PlayerState;

Defined in: packages/player/src/state.ts:1008

The pure state reducer: (state, event, context) → state.

Every PlayerState in the system comes from here. It performs no I/O, reads no clock, and returns the same object identity when an event changes nothing — so onStateChange never fires spuriously.

Parameters

Parameter	Type	Description
state	PlayerState	The previous snapshot.
event	PlayerEvent	One translated event (see PlayerEvent).
context	ReducerContext	Injected clock / time-pos / current URI.

Returns

PlayerState

The next snapshot, or state unchanged.
