Trait GenericUuid

pub trait GenericUuid {
    // Required methods
    fn from_untyped_uuid(uuid: Uuid) -> Self
       where Self: Sized;
    fn into_untyped_uuid(self) -> Uuid
       where Self: Sized;
    fn as_untyped_uuid(&self) -> &Uuid;
}

A trait abstracting over typed and untyped UUIDs.

This can be used to write code that’s generic over TypedUuid, Uuid, and other types that may wrap TypedUuid (due to e.g. orphan rules).

This trait is similar to From, but a bit harder to get wrong – in general, the conversion from and to untyped UUIDs should be careful and explicit.

Required Methods

fn from_untyped_uuid(uuid: Uuid) -> Self

where Self: Sized,

Creates a new instance of Self from an untyped Uuid.

fn into_untyped_uuid(self) -> Uuid

where Self: Sized,

Converts self into an untyped Uuid.

fn as_untyped_uuid(&self) -> &Uuid

Returns the inner Uuid.

Generally, into_untyped_uuid should be preferred. However, in some cases it may be necessary to use this method to satisfy lifetime constraints.
