Last updated: 2026-09-09

Package: compute.profiling | Status: source-declared

Tags: compute, compute.profiling, cpu, method, profiling, source-example, thing, yeho

Collect and describe compute timing, work, and profiling records.

```yh
external thing memoryTimeline
```

- text label: Stores label as text.
- list of memorySample samples: Stores samples as list of memorySample.
- text note: Stores note as text.
- memoryTimeline(text label, text note): Memory timeline.
- AddSample(memorySample sample): Add sample.
- SampleCount() returns int: Sample count.
- PeakBytes() returns int: Peak bytes.
- TotalDeltaBytes() returns int: Total delta bytes.
- TotalReusedBytes() returns int: Total reused bytes.
- Describe() returns text: Describe.

## Use memoryTimeline

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.profiling

// Collect and describe compute timing, work, and profiling records.
memoryTimeline sample = memoryTimeline("Player health", "note")
Console.Log(Text.From(sample.label))

```

Save this beside start.yh as project.mech:

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.
