Struct Edge 

pub struct Edge {
    pub id: EdgeId,
    pub etype: String,
    pub src: NodeId,
    pub dst: NodeId,
    pub props: BTreeMap<String, Ipld>,
    pub extra: BTreeMap<String, Ipld>,
}

A typed, directed link between two Nodes.

Fields

id: EdgeId

Stable edge identity. Survives property edits.

etype: String

Free-form edge-type label ("knows", "cites", …).

src: NodeId

Source NodeId.

dst: NodeId

Destination NodeId.

props: BTreeMap<String, Ipld>

Edge properties. Values are any DAG-CBOR value.

extra: BTreeMap<String, Ipld>

Forward-compat extension map per SPEC §3.2.

Implementations

impl Edge

pub const KIND: &'static str = "edge"

The _kind discriminator for edges. "edge" on the wire.

pub fn new( id: EdgeId, etype: impl Into<String>, src: NodeId, dst: NodeId, ) -> Self

Construct an edge with no properties.

pub fn with_prop(self, key: impl Into<String>, value: impl Into<Ipld>) -> Self

Attach a property. Returns self for chaining.

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<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

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 Serialize for Edge

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for Edge

impl StructuralPartialEq for Edge
