️ Pipeline Registry Generator (v1.50.0)

Both REslava.Result.Flow and REslava.ResultFlow now emit an additional always-on generated file alongside the existing *_Flows.g.cs:

obj/Generated/.../OrderService_PipelineRegistry.g.cs

For every class that has at least one [ResultFlow] method, the generator produces a companion {ClassName}_PipelineRegistry partial class with two constants per method:

// List of all pipeline method names in this class
public const string _Methods = "[\"PlaceOrder\",\"CancelOrder\"]";

// Rich metadata per method — parse with JsonSerializer.Deserialize
public const string PlaceOrder_Info = "{\"returnType\":\"Order\",\"nodeCount\":5,\"nodeKinds\":[\"Root\",\"Bind\",\"Gatekeeper\",\"Tap\",\"Terminal\"],\"errorTypes\":[\"ValidationError\",\"NotFoundError\"],\"hasDiagram\":true,\"sourceLine\":42}";
public const string CancelOrder_Info = "{\"returnType\":\"Result\",\"nodeCount\":3,\"nodeKinds\":[\"Root\",\"Gatekeeper\",\"Terminal\"],\"errorTypes\":[\"NotFoundError\"],\"hasDiagram\":true,\"sourceLine\":78}";

Usage:

// Read all pipeline names
var methods = JsonSerializer.Deserialize<string[]>(OrderService_PipelineRegistry._Methods)!;

// Read metadata for a specific method
var info = JsonSerializer.Deserialize<JsonElement>(OrderService_PipelineRegistry.PlaceOrder_Info);
int nodeCount = info.GetProperty("nodeCount").GetInt32(); // 5
string returnType = info.GetProperty("returnType").GetString()!; // "Order"

_Info JSON fields:

Field	Type	Description
returnType	string	Inner T from Result<T> / Result<T,TError> — "void" for non-generic
nodeCount	int	Number of rendered pipeline nodes
nodeKinds	string[]	Ordered node-kind names (Root, Bind, Gatekeeper, Tap, Terminal, …)
errorTypes	string[]	Distinct error type names extracted from the pipeline
hasDiagram	bool	true when a *_Flows.g.cs companion constant also exists
sourceLine	int	1-based line number of the [ResultFlow] method declaration

To disable registry generation for a specific project, add to its .csproj:

<PropertyGroup>
  <ResultFlowRegistry>false</ResultFlowRegistry>
</PropertyGroup>
