TimeWarp.Mediator.Generators

Source generator for TimeWarp Mediator 15.0. It emits one internal mediator. Send returns the handler ValueTask. The host supplies IServiceProvider, and registered pipeline behaviors are woven. The path is trim and NativeAOT safe.

Install

dotnet add package TimeWarp.Mediator --version 15.0.0-beta.2
dotnet add package TimeWarp.Mediator.Generators --version 15.0.0-beta.2

Without --version, dotnet add package TimeWarp.Mediator resolves 14.0.0, the reflection runtime. Drop the flag when 15.0 is the stable package.

Generators does not bring TimeWarp.Mediator with it. Keep both on the same version. TWM001–TWM004 ship inside TimeWarp.Mediator. This package reports TWM007, TWM008, TWM010, and TWM011, and in a generator host it also reports TWM001–TWM003.

Example

using Microsoft.Extensions.DependencyInjection;
using TimeWarp.Mediator;
using TimeWarp.Mediator.Generated;

ServiceCollection services = new();
services.AddGeneratedMediator();
using ServiceProvider provider = services.BuildServiceProvider();
using IServiceScope scope = provider.CreateScope();
string reply = await scope.ServiceProvider.GetRequiredService<ISender>().Send(new Ping());

public sealed class Ping : IRequest<string> { }

public sealed class PingHandler : IRequestHandler<Ping, string>
{
  public ValueTask<string> Handle(Ping request, CancellationToken cancellationToken) =>
    ValueTask.FromResult("Pong");
}

The host that references this package is a graph member. A library opts in with [assembly: MediatorAssembly] and does not reference this package. Register a pipeline behavior with [assembly: MediatorBehavior(typeof(MyBehavior<,>))]. AddGeneratedMediator() lives in the generated namespace (TimeWarp.Mediator.Generated unless TimeWarpMediatorNamespace is set).

Migration

15.0 is a breaking release.

Handlers and ISender / IPublisher return ValueTask. Behaviors take MessageHandlerDelegate<TRequest, TResponse> and call next(request, cancellationToken).
TimeWarp.Mediator targets net10.0 and net11.0. The generator itself is netstandard2.0 because Roslyn loads it. The Roslyn floor is Microsoft.CodeAnalysis.CSharp 5.0.0.
A missing or duplicate handler is a build error (TWM001, TWM002).
TimeWarpMediatorProfile is removed. Tooling reads [assembly: GeneratedMediator(typeof(Mediator))] and MediatorManifest version 2.

Steps: Migration to 15.0.
