Fuxion.Analyzers.Abstractions

Attribute definitions for Fuxion Roslyn analyzers.

?? Installation

dotnet add package Fuxion.Analyzers.Abstractions

?? What's Included

This package contains only the attribute definitions used by Fuxion analyzers:

  • [RequiresNotNull] - Marks properties/methods that throw when accessed with null
  • [HasMembersRequiringNotNull] - Marks types containing members that require non-null (workaround for extension members)

?? Usage Scenarios

Scenario 1: Using with Fuxion (Automatic)

If you install Fuxion, you automatically get this package transitively:

<PackageReference Include="Fuxion" Version="1.0.0" />

Scenario 2: Using Analyzers Only

If you want to use Fuxion analyzers without the full Fuxion runtime:

<PackageReference Include="Fuxion.Analyzers" Version="1.0.0" />

You get:

  • ? Analyzer attributes (this package)
  • ? Compile-time checks (Fuxion.Analyzers)
  • ? NO Fuxion runtime (~500KB saved)

Scenario 3: Your Own Library

Mark your own members with null-safety attributes:

using Fuxion.Analyzers;

public class MyClass
{
    private string? _value;
    
    [RequiresNotNull]
    public string Value 
    { 
        get => _value ?? throw new ArgumentNullException();
        set => _value = value;
    }
}

Users of your library will get FX001 warnings if they have Fuxion.Analyzers installed.

?? Attributes

[RequiresNotNull]

Indicates a member throws ArgumentNullException when accessed with null.

Targets: Properties, Methods

Example:

[RequiresNotNull]
public string Name { get; set; }

[HasMembersRequiringNotNull]

Indicates a type contains members that require non-null (workaround for C# 14 extension members).

Targets: Classes, Structs

Example:

[HasMembersRequiringNotNull("Pod", "Json")]
public class FuxionExtensions<T> where T : notnull
{
    public T Value { get; }
}
