Struct NodeSpan 

pub struct NodeSpan {
    pub node_id: String,
    pub started_ts: Option<DateTime<Utc>>,
    pub finished_ts: Option<DateTime<Utc>>,
    pub duration_ms: Option<u64>,
    pub outcome: String,
    pub cache_tier: Option<String>,
    pub error: Option<String>,
    pub effectful: bool,
}

One execution span of a node, in event order. A node appears once per execution (re-runs and stream chunks produce separate spans).

Fields

node_id: String

Graph node this span belongs to.

started_ts: Option<DateTime<Utc>>

Envelope timestamp of the opening event.

finished_ts: Option<DateTime<Utc>>

Envelope timestamp of the closing event.

duration_ms: Option<u64>

Wall time between the two envelope timestamps.

outcome: String

completed | failed | cache_hit | running.

cache_tier: Option<String>

Cache tier that served a hit (memory, local, …).

error: Option<String>

Failure message when outcome is failed.

effectful: bool

The node was a step (from NodeStarted); defaults for spans reconstructed from logs that predate the field.
