# prefixed

Wraps Match AST nodes with a structural Route prefix.

## Signatures

```ts
export declare const prefixed: (matches: ReadonlyArray<MatchAst>, prefix: RouteAst) => MatchAst.Prefixed;
```

## Why

Nested tables can be mounted without rewriting child paths.

## Ownership and lifetime

`prefixed` returns a fresh plain AST node immediately and retains any supplied child nodes or arrays by reference; it acquires no external resource.
