Struct Binding 

pub struct Binding {
    pub subject: BindingEndpoint,
    pub target: BindingEndpoint,
    pub kind: Option<String>,
    pub meta: Value,
}

Persisted relationship between graph-local content and a knowledge source anchor.

Fields

subject: BindingEndpoint

Stable local endpoint inside this graph.

target: BindingEndpoint

Stable target endpoint, usually an opaque host-owned source anchor.

kind: Option<String>

Optional domain-specific relationship label.

meta: Value

Arbitrary domain metadata.

Implementations

impl Binding

pub fn new(subject: BindingEndpoint, target: BindingEndpoint) -> Self

pub fn graph_local_to_source( subject: GraphLocalBindingTarget, source_id: impl Into<String>, payload: Value, ) -> Self

pub fn node_to_source( node: NodeId, source_id: impl Into<String>, payload: Value, ) -> Self

pub fn with_kind(self, kind: impl Into<String>) -> Self

pub fn with_meta(self, meta: Value) -> Self

Trait Implementations

impl Clone for Binding

fn clone(&self) -> Binding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Binding

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Binding

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Binding

fn eq(&self, other: &Binding) -> 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 Binding

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
