# close

Marks dialog state closed without requesting native cancellation.

## Signatures

```ts
export declare function close<E, R>(state: RefSubject.RefSubject<State, E, R>): Effect.Effect<State, E, R>;
```

## Why

Programmatic close is distinct from `requestClose`, which runs the browser's
cancelable close-request lifecycle.

## Ownership and lifetime

The Effect updates existing state and acquires no resource.

## Examples

```ts
import { Effect } from "effect"
import * as Dialog from "@typed/ui/Dialog"

const program = Effect.gen(function* () {
  const state = yield* Dialog.makeState({ open: true })
  yield* Dialog.close(state)
})
```
