DTOMaker.CLI 1.9.2-dev

DTOMaker

Warning: This is pre-release software under active development. Breaking changes may occur.

Model-driven compile-time source generators for quickly creating polymorphic, freezable DTOs (Data Transport Objects) supporting various serialization protocols.

Features

• Models defined via C# interfaces with attributes.
  • Source generators create implementations at compile time.
• Properties can be basic .NET types such as integers, floats, strings, Guid, etc.
  • Raw byte arrays are supported using the built-in Octets type.
  • Other common types such as DateTime, DateTimeOffset, TimeSpan are supported by built-in converters.
  • User-defined value types can be supported via user-defined converters to built-in types.
• Nullable types.
• Polymorphic types.
• Freezable types: Instances are mutable until frozen.
• Serialization protocols:
  • JSON via System.Text.Json
  • JSON via Newtonsoft.Json
  • MessagePack 2.x
  • MemBlocks
• Collections. Collections based on balanced binary trees are supported.

Example

using DTOMaker.Models;
namespace MyModels;
[Entity(1)] public interface INode : IEntityBase
{
    [Member(1)] String Key { get; set; } 
}
[Entity(2)] public interface IStringNode : INode
{
    [Member(1)] String Value { get; set; } 
}
[Entity(3)] public interface INumberNode : INode
{
    [Member(1)] Int64 Value  { get; set; } 
}
[Entity(4)] public interface ITree : IEntityBase
{
    [Member(1)] ITree? Left  { get; set; }
    [Member(2)] ITree? Right { get; set; }
    [Member(3)] INode? Node  { get; set; }
}

Development

Coming soon

• more custom (ref and value) type converters

Coming later

• incremental serialization
• MessagePack 3.x serialization
• Orleans serialization
• Protobuf.Net serialization
• model.json generation
• command-line alternative
• variant native type support
• variable length arrays
• logical value equality
• common pattern extensions
