Enum DescribeValue 

pub enum DescribeValue {
    Handle(HandleId),
    Rendered(Value),
}

Per-node cache value in describe output. Surfaced as value: <u64> when produced by Graph::describe (raw handle view), or as value: <T> when produced by Graph::describe_with_debug (binding-rendered view). Serialized uniformly without an enum tag — consumers see either a number or whatever JSON shape the binding emits.

Variants

Handle(HandleId)

Raw handle view. Default for Graph::describe. The serialized JSON is a Number (the u64 raw view of the handle).

Rendered(Value)

Binding-rendered view. Produced by Graph::describe_with_debug via the supplied DebugBindingBoundary. The serialized JSON is whatever shape the binding’s handle_to_debug returned (string, number, object — fully under binding control).

Trait Implementations

impl Clone for DescribeValue

fn clone(&self) -> DescribeValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DescribeValue

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

Formats the value using the given formatter.

impl PartialEq for DescribeValue

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

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

Serialize this value into the given Serde serializer.
