Struct ServiceCookie

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

Cookie of a service.

ServiceCookies are chosen by the broker when creating a service. They ensure that services, created and destroyed over time with the same ServiceUuid and on the same object, can still be distinguished.

Tuple Fields

0: Uuid

Implementations

impl ServiceCookie

pub const NIL: Self

Nil ServiceCookie (all zeros).

pub fn new_v4() -> Self

Creates a ServiceCookie with a random v4 UUID.

Examples

let service_cookie = ServiceCookie::new_v4();

pub const fn is_nil(self) -> bool

Checks if the id is nil (all zeros).
