# `Ash.Type.UUIDv7`
[🔗](https://github.com/ash-project/ash/blob/v3.31.2/lib/ash/type/uuid_v7.ex#L5)

Represents a UUID.

A builtin type that can be referenced via `:uuid_v7`

### Constraints

* `:strict?` (`t:boolean/0`) - Requires the value to actually be a version 7 UUID. Recommended for externally-supplied values: without it, any well-formed UUID passes input casting, but non-v7 values cannot be loaded back from storage. The default value is `false`.

# `handle_change?`

# `prepare_change?`
