WriterPipe

WriterPipe.Create() aggregates writers into one.

IWriterToRef<int, int> writerX2 = DelegateWriter.Reader<int, int>(x => x * 2);
IWriterToRef<int, int> writerX3 = DelegateWriter.Reader<int, int>(x => x * 3);
IWriterToRef<int, int> writerX5 = DelegateWriter.Reader<int, int>(x => x * 5);

IWriterBase<int, int> pipe = WriterPipe.Create<int, int>(writerX2, writerX3, writerX5);

// "30"
WriteLine(pipe.Read(1));

Deconstructer piped to constructor creates a converter writer.

// Create deconstructor
DeconstructorRequest myStructRequest = new DeconstructorRequest(typeof(MyStruct));
IWriterToRef<MyStruct, ValueTuple<int>> myStructDeconstructor = 
    Services.Create(Avalanche.Accessor.Dto.Module.Instance)
    .GetRequired<DeconstructorRequest, IWriterToRef<MyStruct, ValueTuple<int>>>(myStructRequest);

// Create constructor
ConstructorRequest myClassRequest = new ConstructorRequest(typeof(MyClass));
IWriterToRef<ValueTuple<int>, MyClass> myClassConstructor = Services.Create(Avalanche.Accessor.Dto.Module.Instance, CachePolicies.Default).GetRequired<ConstructorRequest, IWriterToRef<ValueTuple<int>, MyClass>>(myClassRequest);

// Pipe deconstructor -> constructor
IWriterBase<MyStruct, MyClass> pipe = WriterPipe.Create<MyStruct, MyClass>(myStructDeconstructor, myClassConstructor);

// Convert MyStruct to MyClass
MyClass myClass = pipe.Read(new MyStruct(99));

public record MyClass(int value);
public record struct MyStruct(int value);

WriterPipeRequest.Create(writers) is a request to create a pipe of writers.

// Deconstructor request
ConstructorRequest myClassConstructorRequest = new ConstructorRequest(typeof(MyClass));
// Constructor request
DeconstructorRequest myStructDeconstructorRequest = new DeconstructorRequest(typeof(MyStruct));
// Pipe deconstructor -> constructor request
WriterPipeRequest pipeRequest = WriterPipeRequest.Create(myStructDeconstructorRequest, myClassConstructorRequest);

// Request pipe
IWriterBase<MyStruct, MyClass> pipe = Services.Create(Avalanche.Accessor.Dto.Module.Instance, CachePolicies.Default).GetRequired<WriterPipeRequest, IWriterBase<MyStruct, MyClass>>(pipeRequest);

// Convert MyStruct to MyClass
MyClass myClass = pipe.Read(new MyStruct(99));
