        fact: FactId,
    },

        fact: FactId,

}

Errors returned while resolving a gatekeep fact into a keepsake target.

Variants

MissingBinding

The resolver has no binding for the requested fact.

Fields

fact: FactId

Unbound fact id.

MissingSubjectSlot

The binding targets a request-scoped subject slot missing from the context.

Fields

fact: FactId

Fact whose binding needs the subject.

slot: SubjectSlot

Missing subject slot.

Subject

Gatekeep and keepsake subject validation drifted apart.

Fields

fact: FactId

Fact whose target subject could not be built.

source: KeepsakeError

Validation failure from keepsake.
