Struct WorkerPhaseTimings 

pub struct WorkerPhaseTimings {
    pub forward_wall_ms: f64,
    pub backward_wall_ms: f64,
    pub fwd_setup_ms: f64,
    pub bwd_setup_ms: f64,
}

Per-worker timing payload for TrainingEvent::WorkerTiming.

Names the four populated values explicitly. Replaces the previous [f64; 16] payload where 12 of 16 slots were always zero on per-worker events. WorkerPhaseTimings is 4 × f64 = 32 bytes; the previous payload was 128 bytes (75% waste).

On Forward-phase events, forward_wall_ms and fwd_setup_ms are populated; the backward fields are 0. On Backward-phase events, backward_wall_ms and bwd_setup_ms are populated; the forward fields are 0.

The writer adapter in training_output.rs maps these four fields into the unchanged 16-wide cobre_io::WorkerTimingRecord via the WORKER_TIMING_SLOT_* constants, preserving the Parquet output schema.

Fields

forward_wall_ms: f64

Forward-pass wall time in ms (populated on Forward; 0 on Backward).

backward_wall_ms: f64

Backward-pass wall time in ms (populated on Backward; 0 on Forward).

fwd_setup_ms: f64

Forward setup time in ms (populated on Forward; 0 on Backward).

bwd_setup_ms: f64

Backward setup time in ms (populated on Backward; 0 on Forward).

Trait Implementations

impl Clone for WorkerPhaseTimings

fn clone(&self) -> WorkerPhaseTimings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WorkerPhaseTimings

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

Formats the value using the given formatter.

impl Default for WorkerPhaseTimings

fn default() -> WorkerPhaseTimings

Returns the “default value” for a type.

impl PartialEq for WorkerPhaseTimings

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