Attributes

Every attribute Trax reads, and what each one changes. They all live in Trax.Effect.Attributes, in the Trax.Effect package, so a train library can carry them without referencing the API, scheduler or GraphQL packages that act on them.

using Trax.Effect.Attributes;
 
[TraxMutation]
[TraxAuthorize(Roles = "Admin")]
[TraxConcurrencyLimit(10)]
public class RefundOrderTrain : ServiceTrain<RefundInput, RefundResult>, IRefundOrderTrain { ... }
 
public record RefundInput(long OrderId, [property: TraxSensitive] string ApprovalCode);
