5/// Represents different types of objects in the SpiceDB authorization system.
6///
7/// `SpiceDbObject` is used to identify resources and subjects when performing
8/// permission checks. Each variant represents a different type of entity in your
9/// application's domain model.
10///
11/// # Object Types
12///
13/// - **Server** - A server/workspace that contains channels, users, and roles
14/// - **Channel** - A communication channel within a server
15/// - **User** - A user/subject that can have permissions
16/// - **PermissionOverride** - A permission override rule
17///
18/// # Examples
19///
20/// ```no_run
21/// use authz::{SpiceDbObject, SpiceDbRepository, Permissions};
22///
23/// # async fn example(repo: SpiceDbRepository) {
24/// // Check if a user can view a channel
25/// let result = repo.check_permissions(
26///     SpiceDbObject::Channel("general-chat".to_string()),
27///     Permissions::ViewChannels,
28///     SpiceDbObject::User("user-123".to_string()),
29/// ).await;
30///
31/// // Check if a user is a server admin
32/// let is_admin = repo.check_permissions(
33///     SpiceDbObject::Server("my-server".to_string()),
34///     Permissions::Administrator,
35///     SpiceDbObject::User("user-456".to_string()),
36/// ).await.has_permissions();
37/// # }

42/// Each `SpiceDbObject` is converted into a SpiceDB `ObjectReference` when
43/// communicating with the SpiceDB API. The object type determines the namespace
44/// used in SpiceDB's schema.
