Struct RelationTuple 

pub struct RelationTuple {
    pub object: Object,
    pub relation: Relation,
    pub user: User,
}

The core relation tuple, representing a single permission assertion. This is the atomic unit of authorization data. e.g., (doc:readme#owner@user:alice)

Fields

object: Object

Relationship resource object.

relation: Relation

Relationship relation.

user: User

Relationship subject.

Implementations

impl RelationTuple

pub fn new(object: Object, relation: Relation, user: User) -> Self

Creates a relationship tuple.

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

Validates this relationship tuple.

Errors

Returns DomainError when any tuple component violates public identifier grammar or byte limits.

Trait Implementations

impl Clone for RelationTuple

fn clone(&self) -> RelationTuple

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationTuple

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RelationTuple

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 RelationTuple

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 RelationTuple

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&RelationTuple> for Relationship

type Error = DomainError

The type returned in the event of a conversion error.

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

Performs the conversion.
