Struct Relationship 

pub struct Relationship {
    pub resource: Option<ObjectReference>,
    pub relation: String,
    pub subject: Option<SubjectReference>,
    pub optional_caveat: Option<ContextualizedCaveat>,
    pub optional_expires_at: Option<Timestamp>,
}

Relationship specifies how a resource relates to a subject. Relationships form the data for the graph over which all permissions questions are answered.

Fields

resource: Option<ObjectReference>

resource is the resource to which the subject is related, in some manner

relation: String

relation is how the resource and subject are related.

subject: Option<SubjectReference>

subject is the subject to which the resource is related, in some manner.

optional_caveat: Option<ContextualizedCaveat>

optional_caveat is a reference to a the caveat that must be enforced over the relationship

optional_expires_at: Option<Timestamp>

optional_expires_at is the time at which the relationship expires, if any.

Trait Implementations

impl Clone for Relationship

fn clone(&self) -> Relationship

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relationship

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

Formats the value using the given formatter.

impl Default for Relationship

fn default() -> Self

Returns the “default value” for a type.

impl Message for Relationship

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Relationship

fn eq(&self, other: &Relationship) -> 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.
