Hide private partial class/struct members

I am generating code based on a given class, this partial class contains a generated public interface and generated private members. Is it possible to hide the visibility of private members for the original non-generated class? Some code example

[System]
internal partial class IterativeSystem
{
    [SystemCall]
    public void Do(int a, ref int b)
    {
        
    }
}

[System]
internal partial class IterativeSystem
{
    [SystemCall]
    public void Do(int a, ref int b)
    {
        
    }
}

internal partial class IterativeSystem
{
    private static Type[] _mutTypes = [typeof(int)];
    private static Type[] _readTypes = [typeof(int)];
    public ReadOnlySpan<Type> MutTypes => _mutTypes;
    public ReadOnlySpan<Type> ReadTypes => _readTypes;

    public void Update()
    {
        // __DoCall(IRuntimeContext.Current.World);
    }

    private readonly QueryDescription __DoQuery;
    private void __DoCall(World world)
    {
        var query = world.Query(in __DoQuery);
        foreach (ref var chunk in query)
        {
            var componentsFirst = chunk.GetFirst<int, int>();
            foreach (var entityIndex in chunk)
            {
                ref var t0Component = ref Unsafe.Add(ref componentsFirst.t0, entityIndex);
                ref var t1Component = ref Unsafe.Add(ref componentsFirst.t1, entityIndex);
                Do(t0Component, ref t1Component);
            }
        }
    }
}

internal partial class IterativeSystem
{
    private static Type[] _mutTypes = [typeof(int)];
    private static Type[] _readTypes = [typeof(int)];
    public ReadOnlySpan<Type> MutTypes => _mutTypes;
    public ReadOnlySpan<Type> ReadTypes => _readTypes;

    public void Update()
    {
        // __DoCall(IRuntimeContext.Current.World);
    }

    private readonly QueryDescription __DoQuery;
    private void __DoCall(World world)
    {
        var query = world.Query(in __DoQuery);
        foreach (ref var chunk in query)
        {
            var componentsFirst = chunk.GetFirst<int, int>();
            foreach (var entityIndex in chunk)
            {
                ref var t0Component = ref Unsafe.Add(ref componentsFirst.t0, entityIndex);
                ref var t1Component = ref Unsafe.Add(ref componentsFirst.t1, entityIndex);
                Do(t0Component, ref t1Component);
            }
        }
    }
}

Is there some standard KeyValue collection allowing adding by value and retrive by key, not dict?

Something like this

public interface IKeyd<TKey> where TKey: IEquatable<TKey>
{
    public TKey Key { get; }
}
public class KeyValueCollection<TKey, TValue> where TValue: IKeyd<TKey> where TKey: IEquatable<TKey>
{
    private Dictionary<TKey, TValue> _keyValues = new();
    public void Add(TValue value)
    {
        _keyValues.Add(value.Key, value);
    }
    public bool TryGetValue(TKey key, out TValue value)
    {
        return _keyValues.TryGetValue(key, out value);
    }
    public bool Contains(TValue value)
    {
        return _keyValues.ContainsKey(value.Key);
    }
    public bool Contains(TKey key)
    {
        return _keyValues.ContainsKey(key);
    }
    public bool Remove(TKey key)
    {
        return _keyValues.Remove(key);
    }
    public bool Remove(TValue value)
    {
        return _keyValues.Remove(value.Key);
    }
}

public interface IKeyd<TKey> where TKey: IEquatable<TKey>
{
    public TKey Key { get; }
}
public class KeyValueCollection<TKey, TValue> where TValue: IKeyd<TKey> where TKey: IEquatable<TKey>
{
    private Dictionary<TKey, TValue> _keyValues = new();
    public void Add(TValue value)
    {
        _keyValues.Add(value.Key, value);
    }
    public bool TryGetValue(TKey key, out TValue value)
    {
        return _keyValues.TryGetValue(key, out value);
    }
    public bool Contains(TValue value)
    {
        return _keyValues.ContainsKey(value.Key);
    }
    public bool Contains(TKey key)
    {
        return _keyValues.ContainsKey(key);
    }
    public bool Remove(TKey key)
    {
        return _keyValues.Remove(key);
    }
    public bool Remove(TValue value)
    {
        return _keyValues.Remove(value.Key);
    }
}

Delegate caching. Is it safe to use or some dirty hack to avoid? (code below)

Here's some delegate caching into struct...

using System;

public class InstanceHandler<T> where T : InstanceHandler<T>
{
    public static T _instance { get; private set; }
    public InstanceHandler() => _instance = (T)this;

    public readonly struct valuedelegate
    {
        private readonly Action _instAction;
        public valuedelegate(Action<T> action)
        {
            T caller = _instance;
            _instAction = () => action.Invoke(caller);
        }
        public void Invoke()=> _instAction();
        public static implicit operator Action(valuedelegate d) => d._instAction;
    }
    public readonly struct valuedelegate<N>
    {
        private readonly Action<N> _instAction;
        public valuedelegate(Action<T, N> action)
        {
            T caller = _instance;
            _instAction = x => action.Invoke(caller, x);
        }
        public void Invoke(N val)=> _instAction(val);
        public static implicit operator Action<N>(valuedelegate<N> v) => v._instAction;
    }
}

abstract class example : InstanceHandler<example>
{
    public void Do() { }
    public void Do(int l) { }
    methods m;
    public class methods
    {
        public valuedelegate a = new valuedelegate((x) => x.Do());
        public valuedelegate<int> b = new valuedelegate<int>((x, z) => x.Do(z));
    }

    public example():base()
    {
        m = new methods();
    }

    public void DoElse()
    {
        m.a.Invoke();
        m.b.Invoke(30);
    }

}

using System;

public class InstanceHandler<T> where T : InstanceHandler<T>
{
    public static T _instance { get; private set; }
    public InstanceHandler() => _instance = (T)this;

    public readonly struct valuedelegate
    {
        private readonly Action _instAction;

        {
            T caller = _instance;
            _instAction = () => action.Invoke(caller);
        }
        public void Invoke()=> _instAction();
        public static implicit operator Action(valuedelegate d) => d._instAction;
    }
    public readonly struct valuedelegate<N>
    {
        private readonly Action<N> _instAction;
        public valuedelegate(Action<T, N> action)
        {
            T caller = _instance;
            _instAction = x => action.Invoke(caller, x);
        }
        public void Invoke(N val)=> _instAction(val);
        public static implicit operator Action<N>(valuedelegate<N> v) => v._instAction;
    }
}

abstract class example : InstanceHandler<example>
{
    public void Do() { }
    public void Do(int l) { }
    methods m;
    public class methods
    {
        public valuedelegate a = new valuedelegate((x) => x.Do());
        public valuedelegate<int> b = new valuedelegate<int>((x, z) => x.Do(z));
    }

    public example():base()
    {
        m = new methods();
    }

    public void DoElse()
    {
        m.a.Invoke();
        m.b.Invoke(30);
    }

Any GUI tool for editing class instance and save to JSON?

I'm creating game tutorial system and want easily edit it's states, conditions etc.. So I have some interfaces as ITutorial, IAction, ICondition, and some implementations as Tutorial, ActionFoo, ActionBar, IfFooBar etc. Is there any gui tool, where i can choose implementation of some interface, fill it's fields and save to json with appropriate class types?

Just read docs about System.Memory<T>, tried it... I there any use cases where array can't do same work?
