Partial Enum

Type-safe, serializable enum-like values that can be defined across multiple files.

How to use

1. Declare a partial struct with [EnumHolder(typeof(YourType))].
2. Add values as public static readonly TypedEnum<YourType> fields on that struct.
3. Extend the same partial struct in other files to add more values.
4. Serialize TypedEnum<YourType> on components — the Inspector shows a dropdown of all registered values.

Compare values with == / !=. Use .Value for the underlying int, or rely on ToString() for the field name.

Setup example

EnumCustomType.cs

using HLMLabs.PartialEnum.Runtime;

[EnumHolder(typeof(EnumCustomType))]
public partial struct EnumCustomType
{
    public static readonly TypedEnum<EnumCustomType> Default = new(0);
    public static readonly TypedEnum<EnumCustomType> ValueA = new(1);
}

EnumCustomType.Impl.cs — additional values in another file

using HLMLabs.PartialEnum.Runtime;

public partial struct EnumCustomType
{
    public static readonly TypedEnum<EnumCustomType> ValueB = new(2);
    public static readonly TypedEnum<EnumCustomType> ValueC = new(3);
}

MyComponent.cs — use in the Inspector

using HLMLabs.PartialEnum.Runtime;
using UnityEngine;

public class MyComponent : MonoBehaviour
{
    [SerializeField] private TypedEnum<EnumCustomType> customType;

    private void Start()
    {
        if (customType == EnumCustomType.ValueB)
            Debug.Log("Value B selected");
    }
}

Each value must have a unique integer. Duplicate values are reported as errors in the Console on domain reload.
