Pure.Chart.Model.HashCodes

Deterministic hash code implementations for chart model abstractions in the Pure ecosystem.

Overview

Pure.Chart.Model.HashCodes provides deterministic, byte-enumerable hash codes for every type in the chart model abstraction layer. Each type wraps one of the Pure.Chart.Model.Abstractions interfaces and produces a stable byte sequence by prepending a fixed 16-byte type-discriminator prefix before hashing the object's fields. The resulting sequences compose cleanly with Pure.HashCodes.DeterminedHash, enabling structural equality checks and content-addressed storage across chart configurations.

API

All types are sealed record and implement IDeterminedHash (which extends IEnumerable<byte>).

Type	Wraps	Hashed fields
ChartHash	IChart	Title, Description, Type, XAxis, YAxis, Series
ChartTypeHash	IChartType	Name
ChartSeriesHash	IChartSeries	Legend, XAxisSource, YAxisSource
AxisHash	IAxis	Legend

All hash types live in the Pure.Chart.Model.HashCodes namespace.

Dependencies

Usage

usingPure.Chart.Model.HashCodes;IChartchart= ...;// any IChart implementation// Enumerate the hash bytes directlybyte[]hash=newChartHash(chart).ToArray();// Compose with other IDeterminedHash valuesIEnumerable<byte>combined=newDeterminedHash(newChartHash(chartA).Concat(newChartHash(chartB)));
