Module PerformanceMetrics 

IPC Performance Metrics

Two complementary observation primitives:

• PerformanceMetrics::Struct - mixed snapshot of throughput, latency (avg
  • peak), success rate, compression, pool, and host resource counters. The natural shape for a single point-in-time readout (get_performance_metrics Tauri command).
• ThroughputMetrics::Struct - directional message/byte counters pinned to a StartTime. The natural shape for rate calculations over a window.

Both files use pub struct Struct so callers spell the full reverse-hierarchical path: IPC::Common::PerformanceMetrics::PerformanceMetrics::Struct.

TODO: zero callers as of 2026-05-02. IPC::StatusReporter defines its own PerformanceMetrics struct with a different shape; the two should converge in a future batch.

Modules

PerformanceMetrics

Aggregate IPC perf snapshot: throughput, latency (avg + peak), compression ratio, pool utilisation, memory + CPU usage, and success/failure counters. RecordMessage updates the running mean latency without bias under high message volume.

ThroughputMetrics

Per-direction message + byte counters with a fixed start time so MessagesPerSecond* / BytesPerSecond* are derivable as divisions over the elapsed period.
