# MatchHandlerReturnValue

The value, Effect, Stream, or Fx accepted as route output.

## Signatures

```ts
export type MatchHandlerReturnValue<A, E, R> = Fx.Fx<A, E, R> | Stream.Stream<A, E, R> | Effect.Effect<A, E, R> | A;
```

## Why

All supported producers normalize to Fx while preserving their errors and service requirements.

## Ownership and lifetime

This union adds no lifetime. Plain values are immediate; Effect, Stream, and Fx resources begin only when the selected handler is run in its route Scope.
