### Features
* Fully abstracts serialization by using compile-time attributes.
* Supports serializing the following:
- Primitives (integers, strings, etc)
- IP Addresses
- BigDecimal
- DateTime, Delta DateTimes
- TimeSpan
- Server.Race
- Server.Map
- Point2D, Point3D, Rect2D, Rect3D
- Existing/New `ISerializable` references
- Lists/Sets of serializable types
- Type with a `Serialize` method and constructor that takes an `IGenericReader`
* Supports forward-only migration
* Supports existing RunUO deserialization for older versions by changing to the following signature:
- `public void OldDeserialize(IGenericReader reader, int version)`
- Must remove deserializing the version since this is already done
* Supports serializing from private fields or custom made properties.
* Types do not require inheriting Item/Mobile. Code gen will fully create `ISerializable` information.
- This is not recommended yet, since it requires wiring to `Persistence` which will cause lots of unresolved symbol errors until code gen is built.
### Example
```cs
using System.Collections.Generic;
namespace Server.Items
{
[Serializable(1)]
public partial class TestItem1 : Item
{
[SerializableField(1)]
[SerializableFieldAttr("[CommandProperty(AccessLevel.Administrator)]")]
private List<Item> _someProperty;
private void Deserialize(IGenericReader reader, int version)
{
}
}
}
```
Generates this:
```cs
namespace Server.Items
{
public partial class TestItem1
{
#pragma warning disable 0414
private const int _version = 1;
#pragma warning restore 0414
[CommandProperty(AccessLevel.Administrator)]
public System.Collections.Generic.List<Server.Item> SomeProperty
{
get => _someProperty;
set
{
if (value != _someProperty)
{
((ISerializable)this).MarkDirty();
_someProperty = value;
}
}
}
public TestItem1(Serial serial) : base(serial)
{
}
public override void Serialize(IGenericWriter writer)
{
var savePosition = ((Server.ISerializable)this).SavePosition;
if (savePosition > -1)
{
writer.Seek(savePosition, System.IO.SeekOrigin.Begin);
return;
}
writer.WriteEncodedInt(_version);
writer.Write(_someProperty);
}
public override void Deserialize(IGenericReader reader)
{
var version = reader.ReadEncodedInt();
if (version < 1)
{
OldDeserialize(reader, version);
((Server.ISerializable)this).MarkDirty();
return;
}
SomeProperty = reader.ReadEntityList<Server.Item>();
}
}
}
```
And this:
```json
{
"version": 1,
"type": "TestItem1",
"properties": [
{
"name": "SomeProperty",
"type": "System.Collections.Generic.List\u003CServer.Item\u003E",
"rule": "ListMigrationRule",
"ruleArguments": [
"Server.Item",
"SerializableInterfaceMigrationRule"
]
}
]
}
```
