Cause.Cause.ReasonProto

Base interface shared by all reason types (Fail, Die, Interrupt).

Details

Every reason carries:

• _tag — discriminant string ("Fail", "Die", or "Interrupt")
• annotations — tracing metadata attached by the runtime
• annotate() — returns a copy with additional annotations

Signature

export interface ReasonProto<Tag extends string> extends Inspectable, Equal {
    readonly [ReasonTypeId]: typeof ReasonTypeId
    readonly _tag: Tag
    readonly annotations: ReadonlyMap<string, unknown>
    annotate(annotations: Context.Context<never> | ReadonlyMap<string, unknown>, options?: {
      readonly overwrite?: boolean | undefined
    }): this
  }
