# PathAst.Literal

An exact literal path or query-value AST node.

## Signatures

```ts
type Literal = {
    type: "literal";
    value: string;
};
```

## Why

Literal nodes constrain matching without adding decoded parameters.

## Ownership and lifetime

`Literal` describes plain readonly AST data. Routes and Matchers retain the concrete nodes they receive by reference; the type itself owns no resource.

## Property: type

Discriminates an exact literal node.

## Property: type: Why

Formatters and match compilers can branch without hidden classes.

## Property: type: Ownership and lifetime

The string literal is stored directly on the plain AST object for that object's lifetime.

## Property: value

Exact source text required by this node.

## Property: value: Why

Literal matching and formatting must preserve the same spelling.

## Property: value: Ownership and lifetime

The node retains the immutable string value and acquires no matcher resource.
