IRequest

Namespace: RA.Utilities.Dispatcher.Abstractions

The IRequest and IRequest<TResponse> marker interfaces identify your requests — the commands and queries of your CQRS application. They carry no members; their job is to give the dispatcher a compile-time contract to dispatch on.

📦 Type Definition​

/// <summary>
/// A marker interface for a feature (command or query).
/// This is used for features that do not return a value.
/// </summary>
public interface IRequest;

/// <summary>
/// A marker interface for a feature (command or query) that returns a value.
/// </summary>
/// <typeparam name="TResponse">The type of the response.</typeparam>
public interface IRequest<TResponse> : IRequest;

Note the difference from some other libraries: TResponse is your plain payload type — the dispatcher wraps it in Result<TResponse> when it returns.

🚀 Usage​

// A command with no return value
public record DeleteProductCommand(int ProductId) : IRequest;

// A query that returns data
public record GetProductQuery(int ProductId) : IRequest<Product>;

// A command that returns the created ID
public record CreateProductCommand(string Name, decimal Price) : IRequest<int>;
