Struct UserRoleAssignment 

pub struct UserRoleAssignment {
    pub id: Uuid,
    pub user_id: Uuid,
    pub role: UserRole,
    pub organization_id: Option<Uuid>,
    pub is_primary: bool,
    pub valid_until: Option<DateTime<Utc>>,
    pub delegated_from_user_id: Option<Uuid>,
    pub created_at: DateTime<Utc>,
    pub updated_at: DateTime<Utc>,
}

Represents an assignment of a role to a user within an optional organization scope.

Story 3.5 — Temporary role delegation (FR8 INV-8)

Two optional fields turn a permanent native assignment into a time-bounded delegated assignment:

• valid_until = None ⇒ permanent / native role (legacy behaviour).
• valid_until = Some(t) ⇒ delegated assignment that auto-expires at t.
• delegated_from_user_id = Some(delegator) ⇒ trail of who delegated the role; used by crate::application::use_cases::RoleDelegationUseCases to enforce the non-transitive invariant (a user cannot re-delegate a role that was itself delegated to them).

Fields

id: Uuid

user_id: Uuid

role: UserRole

organization_id: Option<Uuid>

is_primary: bool

valid_until: Option<DateTime<Utc>>

Story 3.5: end of validity. None = permanent native role.

delegated_from_user_id: Option<Uuid>

Story 3.5: source of the delegation. None = native role. Some(uid) = uid granted this role for a bounded duration.

created_at: DateTime<Utc>

updated_at: DateTime<Utc>

Implementations

impl UserRoleAssignment

pub fn new( user_id: Uuid, role: UserRole, organization_id: Option<Uuid>, is_primary: bool, ) -> Self

Creates a new permanent (native) role assignment.

valid_until and delegated_from_user_id default to None. Use UserRoleAssignment::new_delegated for a time-bounded delegation.

pub fn new_delegated( user_id: Uuid, role: UserRole, organization_id: Option<Uuid>, valid_until: DateTime<Utc>, delegated_from_user_id: Uuid, ) -> Self

Creates a new delegated role assignment (Story 3.5).

A delegated assignment is never the primary role of the target user — keeping the user’s native primary intact for users.role consistency.

pub fn set_primary(&mut self, primary: bool)

pub fn is_delegated(&self) -> bool

True if this assignment is a delegated (non-native) role.

pub fn is_expired(&self) -> bool

True if the assignment carries a valid_until and it is in the past.

A permanent native role (valid_until = None) is never expired.

pub fn is_expired_at(&self, t: DateTime<Utc>) -> bool

Testable variant of is_expired taking an explicit reference time.

pub fn is_currently_active(&self) -> bool

True if the assignment authorises actions right now.

Native (permanent) assignments are always active. Delegated assignments are active iff their window has not elapsed.

Trait Implementations

impl Clone for UserRoleAssignment

fn clone(&self) -> UserRoleAssignment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UserRoleAssignment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UserRoleAssignment

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for UserRoleAssignment

impl From<UserRoleAssignment> for UserRoleAssignmentResponse

fn from(a: UserRoleAssignment) -> Self

Converts to this type from the input type.

impl From<UserRoleAssignment> for RoleDelegationResponse

fn from(a: UserRoleAssignment) -> Self

Converts to this type from the input type.

impl PartialEq for UserRoleAssignment

fn eq(&self, other: &UserRoleAssignment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UserRoleAssignment

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
