Struct RelationTuple 

pub struct RelationTuple {
    pub object: String,
    pub relation: String,
    pub subject: String,
}

A single relationship tuple: (object, relation, subject).

Fields

object: String

Object identifier (e.g. “document:readme”).

relation: String

Relation name (e.g. “viewer”, “owner”, “parent”).

subject: String

Subject — either a direct user ID or a userset reference (e.g. “user:alice” or “group:engineering#member”).

Implementations

impl RelationTuple

pub fn new( object: impl Into<String>, relation: impl Into<String>, subject: impl Into<String>, ) -> Self

Create a new relation tuple.

pub fn parse_subject(&self) -> Option<(&str, &str, Option<&str>)>

Parse the subject’s namespace and optional userset relation.

"user:alice" → ("user", "alice", None) "group:eng#member" → ("group", "eng", Some("member"))

pub fn parse_object(&self) -> Option<(&str, &str)>

Parse the object’s namespace and ID.

"document:readme" → ("document", "readme")

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

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.
