# isWire

Checks if a rendered node is a `Wire`.

## Signatures

```ts
export declare function isWire(node: Rendered): node is Wire;
```

## Why

Wire ranges use a deliberate node-type sentinel rather than an extra wrapper.

## Ownership and lifetime

The guard borrows the value and changes no DOM state.

## Examples

```ts
import { isWire } from "@typed/template/Wire"

const result = isWire(document.createDocumentFragment())
```
