This crate provides a way to specify a stable, unique identifier for Rust 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
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.uuidgenerator.net, which provides a quick way
generate new UUIDs that you can paste into your code.
Provides a statically defined UUID for a Rust type.
Allows the TypeUuid constants to be retrieved via a trait object.
A 128-bit (16 byte) buffer containing the ID.
