type-uuid
This crate provides a way to specify a stable, unique identifier for Rust types.
Assigning UUIDs to Types
This crate provides the TypeUuid
trait, which defines a single const item
UUID
. This value is a byte array containing the raw bytes of the UUID for the
type.
You will have to manually specify the UUID for any type implementing
TypeUuid
, but this crate provides a custom derive to make that easy to do:
use type_uuid::TypeUuid;
#[derive(TypeUuid)]
#[uuid = "d4adfc76-f5f4-40b0-8e28-8a51a12f5e46"]
struct MyType;
While the derive handles the tedious work of converting the UUID into a byte
array suitable for use with the TypeUuid
trait, you'll still need to
generate a valid UUID in order to assign it to your type. To do so, we
recommend using https://www.uuidtools.com/generate/v4, which provides a quick way
generate new UUIDs that you can paste into your code.
