Nitpick.Functional.UnitType 1.0.1

Unit

Unit for C# (Nitpick.Functional.UnitType) plus optional JSON converters.

This repository contains three libraries:

• Nitpick.Functional.UnitType: core Unit type
• Nitpick.Functional.UnitType.SystemTextJson: System.Text.Json converter for Unit
• Nitpick.Functional.UnitType.NewtonsoftJson: Newtonsoft.Json converter for Unit

Packages

dotnet add package Nitpick.Functional.UnitType
dotnet add package Nitpick.Functional.UnitType.SystemTextJson
dotnet add package Nitpick.Functional.UnitType.NewtonsoftJson

Install only the converter package you need for your serializer.

Core usage

using Nitpick.Functional;

Unit value = Unit.Value;
Unit fromTuple = default(ValueTuple);
ValueTuple tuple = Unit.Value;

Console.WriteLine(Unit.Value); // ()

Unit is a readonly struct with a single logical value and implements:

• IEquatable<Unit>
• IComparable<Unit>

JSON converters

Both converters serialize Unit as JSON null and accept only JSON null when deserializing.

System.Text.Json

using Nitpick.Functional;
using System.Text.Json;

var options = new JsonSerializerOptions();
options.Converters.Add(UnitJsonConverter.Instance);

string json = JsonSerializer.Serialize(Unit.Value, options); // "null"
Unit unit = JsonSerializer.Deserialize<Unit>("null", options);

Newtonsoft.Json

using Nitpick.Functional;
using Newtonsoft.Json;

var settings = new JsonSerializerSettings();
settings.Converters.Add(new UnitJsonConverter());

string json = JsonConvert.SerializeObject(Unit.Value, settings); // "null"
Unit unit = JsonConvert.DeserializeObject<Unit>("null", settings);

Release

Version is defined in Version.props.

CI release flow:

1. Set <Version> in Version.props.
2. Create and push tag v<Version> (for example: v1.2.0).
3. Publish a GitHub release for that tag.
4. finish_release workflow publishes packages to NuGet.org and GitHub Packages.
