### Example generator

```csharp

using AttributeSourceGenerator;

using Microsoft.CodeAnalysis;

namespace SourceGenerators;

[Generator]

public sealed class IdentifierSourceGenerator : AttributeIncrementalGeneratorBase

{

    public IdentifierSourceGenerator()

        : base(() => new AttributeIncrementalGeneratorConfiguration()

        {

            MarkerAttributeName = MarkerAttributeName,

            MarkerAttributeSource = MarkerAttributeSource,

            SymbolFilter = FilterType.Struct,

            SourceGenerator = GenerateIdentifier

        })

    {

    }

    private const string MarkerAttributeNamespace = "Domain.Common.Attributes";

    private const string MarkerAttributeName = $"{MarkerAttributeNamespace}.GeneratedIdentifierAttribute`1";

    private static source MarkerAttributeSource = new Source("GeneratedIdentifierAttribute`1", $$"""

        namespace {{MarkerAttributeNamespace}};

        

        [AttributeUsage(AttributeTargets.Struct)]

        public sealed class GeneratedIdentifierAttribute : Attribute;                                                               

        """;

    private static IEnumerable GenerateIdentifier(Symbol symbol)

    {

        return [new Source(symbol.Name, $$"""

            // 

            

            #nullable enable

            

            namespace {{symbol.Namespace}};

            

            partial struct {{symbol.Name}} : IEquatable<{{symbol.Name}}>, IComparable<{{symbol.Name}}>, IComparable

            {

              // Implementation details

            }

            """)];

    }

}

```
