Class ExceptionBehavior<TMessage, TResponse>

Namespace

Trellis.Mediator

Assembly

Trellis.Mediator.dll

Pipeline behavior that catches unhandled exceptions from handlers and converts them to Error.InternalServerError failures. This is a safety net — handlers should not throw, but if they do, this prevents unhandled exceptions from escaping the mediator pipeline.

public sealed class ExceptionBehavior<TMessage, TResponse> : IPipelineBehavior<TMessage, TResponse> where TMessage : IMessage where TResponse : IResult, IFailureFactory<TResponse>

Type Parameters

TMessage

The message type.

TResponse

The response type, constrained to IResult and IFailureFactory<TSelf>.
