Attribute Validators

The field attrribute:

[AttributeUsage(AttributeTargets.Field | AttributeTargets.Property, AllowMultiple = true)]
public sealed class RequiredAttribute : Attribute
{
    private readonly EValidatorSeverity _severity;

    public RequiredAttribute()
    {
        _severity = EValidatorSeverity.Error;
    }
    
    public RequiredAttribute(EValidatorSeverity severity)
    {
        _severity = severity;
    }
}

The validator implements IAttributeValidator<T>, where T is the attribute and will automatically be found by the validator.

public sealed class Validator : IAttributeValidator<RequiredAttribute>
{
    public ValidatorResult Validate(RequiredAttribute attribute, object value)
    {
        var isValid = value is UnityEngine.Object obj ? obj != null : value != null;
        return isValid ? ValidatorResult.Valid : ValidatorResult.Create(attribute._severity, "Value is Null");
    }
}
