FastCloner.SourceGenerator 1.2.1

FastCloner.SourceGenerator

High-performance source generator for deep cloning objects at compile time.

Installation

dotnet add package FastCloner.SourceGenerator

The package is automatically configured as a build-time dependency and won't propagate to consuming projects.

Usage

1. Mark your classes with [FastClonerClonable] attribute:

using FastCloner.SourceGenerator.Shared;

[FastClonerClonable]
public class Person
{
 public string Name { get; set; }
 public int Age { get; set; }
 public List<string> Hobbies { get; set; }
}

2. The generator will create a FastDeepClone() extension method:

var original = new Person { Name = "John", Age = 30, Hobbies = new() { "Reading" } };
var clone = original.FastDeepClone();

Features

• ✅ Zero reflection - all cloning logic is generated at compile time
• ✅ Circular reference detection - automatically handled when needed
• ✅ High performance - up to 60% faster than competing source generators
• ✅ Collections support - List, Dictionary, Arrays, etc.
• ✅ Nullable reference types - full support
• ✅ No partial requirement - works with any class or struct

Requirements

• .NET Standard 2.0+ or .NET 5+
• C# 9.0+ (for source generators)
