# valueTrace

A value trace record carrying label, origin, values, note.

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 valueTrace
```

- text label: Stores label as text.
- text origin: Stores origin as text.
- list of int values: Stores values as list of int.
- text note: Stores note as text.
- valueTrace(text label, text origin, list of int values, text note): Value trace.
- HasValues() returns bool: Has values.
- Count() returns int: Count.
- FirstValue() returns int: First value.
- LastValue() returns int: Last value.
- Minimum() returns int: Minimum.
- Maximum() returns int: Maximum.
- Span() returns int: Span.
- Describe() returns text: Describe.

## Use valueTrace

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.
valueTrace sample = valueTrace("Player health", "origin", [], "note")
Console.Log(Text.From(sample.label))

```

Save this beside start.yh as project.mech:
