Module perf 

Cross-cutting performance instrumentation.

This module provides instruction-count measurement primitives used across endpoints, ops, timers, and background tasks.

It is intentionally crate-level infrastructure, not part of the domain layering (endpoints → ops → model). Instrumentation modules are layer-neutral and may be used anywhere.

Structs

PerfEntry

PerfEntry Aggregated perf counters keyed by kind (endpoint vs timer) and label.

Enums

PerfKey

PerfKey splitting up by Timer type to avoid confusing string comparisons

Constants

PERF_LAST

Last snapshot used by the perf! macro.

Functions

entries

Snapshot all recorded perf counters, sorted by key. Entries are sorted by (kind, label).

perf_counter

Returns the call-context instruction counter for the current execution.

record

Record a counter under the provided key.

record_endpoint

record_timer
