RecordCloner

RecordCloner<T> implements ICloner and IGraphCloner for record like classes and structs.

RecordCloner<MyRecord> cloner =
    new RecordCloner<MyRecord>()
    .SetReadOnly();

RecordCloner.Create(type) also creates cloner.

RecordCloner<MyRecord> cloner =
    (RecordCloner<MyRecord>)
    RecordCloner.Create(typeof(MyRecord))
    .SetReadOnly();

.SetClonerProvider(IProvider<Type, object>) assigns cloner provider for fields for deep cloning.

RecordCloner<MyRecord> cloner =
    new RecordCloner<MyRecord>()
    .SetClonerProvider(ClonerProvider.Cached)
    .SetReadOnly();

Record can be cloned.

// Create cloner
RecordCloner<MyRecord> cloner = new RecordCloner<MyRecord>();
// Create record
MyRecord record1 = new MyRecord(1);
// Clone record
MyRecord clone = cloner.Clone(record1);

public record MyRecord(int Id) : IRecord;

.SetCyclical(true) marks cloner for cyclical records. The ClonerProvider implementation requires the record to have IRecord and ICyclical interfaces.

// Create cloner
RecordCloner<Node> cloner =
    new RecordCloner<Node>()
    .SetCyclical(true)
    .SetClonerProvider(ClonerProvider.Cached)
    .SetReadOnly();
// Create graph
Node node1 = new Node(1);
Node node2 = new Node(2);
Node node3 = new Node(3);
node1.Edges.Add(node2);
node2.Edges.Add(node3);
node3.Edges.Add(node1);
// Clone graph
Node clone1 = cloner.Clone(node1);
// Compare object references
WriteLine(clone1 == node1); // false

public class Node : IRecord, ICyclical
{
    /// <summary>Is possibly cyclical node.</summary>
    [IgnoreDataMember] public bool IsCyclical { get => Edges.Count > 0; set { } }
    public readonly int Id;
    public List<Node> Edges = new List<Node>();
    public Node(int id) => Id = id;
}
