Struct Edge 

pub struct Edge {
    pub from: String,
    pub kind: EdgeKind,
    pub to: String,
}

A directed edge between two knowledge graph nodes. Persisted in SurrealKV as graph:edge:<from>:<kind>:<to>.

Fields

from: String

kind: EdgeKind

to: String

Implementations

impl Edge

pub fn new( from: impl Into<String>, kind: EdgeKind, to: impl Into<String>, ) -> Self

pub fn to_key(&self) -> String

Encode to the SurrealKV key format: graph:edge:<from>:<kind>:<to>.

pub fn from_key(key: &str) -> Option<Self>

Parse an edge back from a graph:edge:... key.

from and to may contain colons (e.g. file:src/main.rs), so the parser scans for kind segments left-to-right and validates that both endpoint values start with known node-key namespaces. This prevents false matches when a slug itself equals a kind name (e.g. gotcha:touched) and skips corrupt persisted keys whose to endpoint is not a real node key.

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 Eq for Edge

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
