Struct ExecutionTrace 

pub struct ExecutionTrace { /* private fields */ }

Execution trace containing recorded operations.

Implementations

impl ExecutionTrace

pub fn new() -> Self

Create a new empty trace.

pub fn with_graph_id(self, graph_id: usize) -> Self

Set the graph ID for this trace.

pub fn add_entry(&mut self, entry: TraceEntry)

Add a trace entry.

pub fn entries(&self) -> &[TraceEntry]

Get all trace entries.

pub fn total_duration(&self) -> Duration

Get the total execution duration.

pub fn total_duration_ms(&self) -> f64

Get the total duration in milliseconds.

pub fn entries_for_node(&self, node_id: usize) -> Vec<&TraceEntry>

Get entries for a specific node.

pub fn critical_path(&self) -> Vec<&TraceEntry>

Get the critical path (longest chain of dependent operations).

Uses dependency tracking via input/output tensor IDs to compute the critical path. The critical path is the longest chain of operations where each depends on the previous, determining the minimum possible execution time.

pub fn critical_path_duration(&self) -> Duration

Get the total critical path duration.

pub fn parallelism_factor(&self) -> f64

Calculate the parallelism factor (total work / critical path time). Values > 1 indicate potential for parallel execution.

pub fn slowest_operations(&self, limit: usize) -> Vec<&TraceEntry>

Get operations sorted by duration (slowest first).

pub fn summary(&self) -> TraceSummary

Generate a summary report.

Trait Implementations

impl Clone for ExecutionTrace

fn clone(&self) -> ExecutionTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionTrace

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

Formats the value using the given formatter.

impl Default for ExecutionTrace

fn default() -> Self

Returns the “default value” for a type.
