Enum User 

pub enum User {
    UserId(String),
    Userset(Object, Relation),
}

Represents either a specific user ID or a reference to a userset (e.g., a group).

Variants

UserId(String)

A specific user, identified by a unique string. e.g., "10", "alice".

Userset(Object, Relation)

A set of users, identified by an object-relation pair. e.g., group:eng#member

Implementations

impl User

pub fn user_id(id: impl Into<String>) -> Self

Creates a direct user subject.

pub fn userset(object: Object, relation: Relation) -> Self

Creates a userset subject.

pub fn validate(&self) -> Result<(), DomainError>

Validates this subject reference.

Errors

Returns DomainError when a direct user id or userset object/relation violates public identifier grammar or byte limits.

Trait Implementations

impl Clone for User

fn clone(&self) -> User

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for User

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for User

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for User

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for User

fn eq(&self, other: &User) -> 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 User

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&User> for SubjectFilter

type Error = ZanzibarError

The type returned in the event of a conversion error.

fn try_from(value: &User) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&User> for SubjectRef

type Error = DomainError

The type returned in the event of a conversion error.

fn try_from(value: &User) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for User
