Struct NodeOverlay 

pub struct NodeOverlay {
    pub status: Option<NodeStatus>,
    pub duration_ms: Option<u64>,
    pub cache_tier: Option<String>,
    pub flags: Vec<String>,
    pub sublabel: Option<String>,
}

Per-node annotation folded into the rendered label and style.

Fields

status: Option<NodeStatus>

How the node finished, driving the status color.

duration_ms: Option<u64>

Total compute time across this node’s executions.

cache_tier: Option<String>

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

flags: Vec<String>

Health flags raised on this node (DEAD_CHANNELS, LEAKAGE, …).

sublabel: Option<String>

Free-form extra label line (appended after the derived parts).

Implementations

impl NodeOverlay

pub fn sublabel_text(&self) -> Option<String>

The extra label line derived from this overlay, e.g. "1.2s · mem hit · ⚠ LEAKAGE". None when there is nothing to show.

pub fn style_class(&self) -> Option<&'static str>

The style class this node gets (mermaid classDef / graphviz fillcolor). Flags win over status: an unhealthy node must stand out even when it completed.
