Struct ChildRun 

pub struct ChildRun {
    pub node: NodeId,
    pub graph_id: GraphId,
    pub run_id: RunId,
    pub root_run_id: RunId,
    pub usage: UsageTotals,
}

A reference to a child run spawned from a node within an enclosing run.

Recorded when a subgraph node embeds and runs a CompiledGraph: the child gets its own run_id while preserving the enclosing run’s root_run_id, so a caller can reconstruct the parent/child run lineage after a run completes. Child runs are surfaced on GraphExecution and embedded into the parent checkpoint metadata under a child_runs array.

Fields

node: NodeId

The embedding node that ran the child graph.

graph_id: GraphId

The graph id of the embedded child.

run_id: RunId

The child run’s own (distinct) run id.

root_run_id: RunId

The shared root run id of the whole recursion tree (preserved from the enclosing run).

usage: UsageTotals

Token usage rolled up from the child run, when the child reported any.

Subgraph children leave this at the default (their usage is tracked by their own model calls); a [crate::graph::subagent_node] sub-agent child folds the delegated harness agent’s [UsageTotals] here so it is visible on the parent GraphExecution rollup.

Trait Implementations

impl Clone for ChildRun

fn clone(&self) -> ChildRun

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChildRun

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChildRun

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ChildRun

impl PartialEq for ChildRun

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
