Struct PartitionTrace 

pub struct PartitionTrace {
    pub layers: Vec<PartitionLayerRecord>,
}

Per-layer records of propagations in application order, accumulated until drained by a driver’s take_trace.

A plain propagate_with run records one partition; term counts are post-truncation, so the transient expansion inside a layer is not captured.

Fields

layers: Vec<PartitionLayerRecord>

One record per layer applied.

Implementations

impl PartitionTrace

pub fn peak_terms(&self) -> Option<usize>

Peak resident term count between layers, summed over partitions, or None for a zero-layer trace.

pub fn total_rows_exchanged(&self) -> u64

Rows moved across partitions over the whole trace.

pub fn imbalance(&self) -> Vec<f64>

Per layer, the maximum input term count over partitions divided by the mean; 1.0 for a layer where every partition was empty.

pub fn local_layers(&self) -> usize

Layers that made no transport call.

pub fn remote_layers(&self) -> usize

Layers that exchanged.

pub fn total_collectives(&self) -> u64

Collective calls over the whole trace, excluding the point-to-point exchanges.

Trait Implementations

impl Clone for PartitionTrace

fn clone(&self) -> PartitionTrace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionTrace

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

Formats the value using the given formatter.

impl Default for PartitionTrace

fn default() -> PartitionTrace

Returns the “default value” for a type.

impl PartialEq for PartitionTrace

fn eq(&self, other: &PartitionTrace) -> 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.
