# Uuid7

Effect Schema and branded string type for RFC UUID version 7 values.

## Signatures

```ts
export declare const Uuid7: Schema.brand<Schema.String, "@typed/id/UUID7">;
```

```ts
export type Uuid7 = typeof Uuid7.Type;
```

## Why

The schema verifies version and variant at transport boundaries; generated ordering is local to one Uuid7State, not a distributed total order.

## Ownership and lifetime

This module-level schema value acquires no resources and is shared; no runtime freezing guarantee is implied.

## Examples

```ts
import { Uuid7 } from "@typed/id/Uuid7"
import { Schema } from "effect"
const id = Schema.decodeUnknownSync(Uuid7)("01890f2e-7d6c-7cc0-98c4-dc0c0c07398f")
```
