Struct Edge

pub struct Edge {
    pub outbound_id: Uuid,
    pub t: Identifier,
    pub inbound_id: Uuid,
}

An edge.

Edges are how you would represent a verb or a relationship in the datastore. An example might be “liked” or “reviewed”. Edges are typed and directed.

Fields

outbound_id: Uuid

The id of the outbound vertex.

t: Identifier

The type of the edge.

inbound_id: Uuid

The id of the inbound vertex.

Implementations

impl Edge

pub fn new(outbound_id: Uuid, t: Identifier, inbound_id: Uuid) -> Edge

Creates a new edge key.

Arguments

• outbound_id: The id of the outbound vertex.
• t: The type of the edge.
• inbound_id: The id of the inbound vertex.

pub fn reversed(&self) -> Edge

Produces a new edge key that is a reversed version of this one; i.e. it has the same type, but the outbound and inbound IDs are flipped.

Trait Implementations

impl Clone for Edge

fn clone(&self) -> Edge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Edge

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Edge

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Edge

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 Ord for Edge

fn cmp(&self, other: &Edge) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Edge

fn eq(&self, other: &Edge) -> 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 PartialOrd for Edge

fn partial_cmp(&self, other: &Edge) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Edge

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
