Struct Role Delegation UseCases &nbsp; Copy item path

impl RoleDelegationUseCases

pub fn new(repo: Arc<dyn RoleDelegationRepository>) -> Self

pub async fn delegate_role( &self, delegator_user_id: Uuid, target_user_id: Uuid, role: UserRole, organization_id: Option<Uuid>, valid_until: DateTime<Utc>, ) -> Result<UserRoleAssignment, AppError>

Delegate a role to another user.

The caller (handler) MUST have already verified that delegator_user_id owns the role to be delegated (via JWT + native assignment lookup); this use-case re-checks the non-transitive invariant by inspecting the persisted assignment(s).

pub async fn revoke_delegation( &self, assignment_id: Uuid, ) -> Result<(), AppError>

Manually revoke a delegation before its term. Idempotent.

pub async fn list_delegations_of( &self, user_id: Uuid, ) -> Result<Vec<UserRoleAssignment>, AppError>

List active delegations involving user_id (received OR granted).
