Struct NodeStepTelemetry 

#[non_exhaustive]
pub struct NodeStepTelemetry { /* private fields */ }

Structured telemetry produced for each node step.

A node step represents a single scheduling decision in which a node consumes zero or more input messages and produces zero or more output messages.

Implementations

impl NodeStepTelemetry

pub const fn new( graph_id: GraphInstanceId, node_index: NodeIndex, node_name: Option<&'static str>, timestamp_start_ns: u64, timestamp_end_ns: u64, duration_ns: u64, processed_count: u64, deadline_ns: Option<u64>, deadline_missed: bool, error_kind: Option<NodeStepError>, ) -> Self

Construct a new NodeStepTelemetry record.

pub const fn graph_id(&self) -> &GraphInstanceId

Returns the identifier of the graph instance this step belongs to.

pub const fn node_index(&self) -> &NodeIndex

Returns the index of the node within the graph.

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

Returns the optional static node name associated with this step.

pub const fn timestamp_start_ns(&self) -> &u64

Returns the step start timestamp in nanoseconds since an arbitrary epoch.

pub const fn timestamp_end_ns(&self) -> &u64

Returns the step end timestamp in nanoseconds since an arbitrary epoch.

pub const fn duration_ns(&self) -> &u64

Returns the step duration in nanoseconds.

pub const fn processed_count(&self) -> &u64

Returns the number of messages processed by this step.

pub const fn deadline_ns(&self) -> &Option<u64>

Returns the optional absolute deadline for this step in nanoseconds.

pub const fn deadline_missed(&self) -> &bool

Returns whether the step exceeded its deadline.

pub const fn error_kind(&self) -> &Option<NodeStepError>

Returns the optional high-level error classification for this step.
