Struct ObjectCookie 

#[repr(transparent)]
pub struct ObjectCookie(pub Uuid);

Cookie of an object.

ObjectCookies are chosen by the broker when creating an object. They ensure that objects, created and destroyed over time with the same ObjectUuid, can still be distinguished.

Tuple Fields

0: Uuid

Implementations

impl ObjectCookie

pub const NIL: Self

Nil ObjectCookie (all zeros).

pub fn new_v4() -> Self

Creates an ObjectCookie with a random v4 UUID.

Examples

let object_cookie = ObjectCookie::new_v4();

pub const fn is_nil(self) -> bool

Checks if the id is nil (all zeros).
