Properties

acquisitions

readonly acquisitions: readonly AcquisitionSnapshot<A>[];

RegistrationSnapshot.acquisitions

---

aliasTarget?

readonly aliasTarget?: {
    readonly bindingId: symbol;
    readonly bindingLabel: string;
};

Defined in: inspection.ts:41

Direct lexical target; acquisition snapshots follow the canonical target.

bindingId

readonly bindingId: symbol;

bindingLabel

readonly bindingLabel: string;

Inherited from

RegistrationSnapshot.aliasTarget

---

bindingId

readonly bindingId: symbol;

Defined in: inspection.ts:37

Stable identity for the canonical graph binding.

Inherited from

RegistrationSnapshot.bindingId

---

bindingLabel

readonly bindingLabel: string;

Defined in: inspection.ts:39

Human-readable binding label.

Inherited from

RegistrationSnapshot.bindingLabel

---

factoryReturnKind

readonly factoryReturnKind: FactoryReturnKind;

}[];

Defined in: inspection.ts:60

Typed-token dependencies declared positionally through service tokens, collection tokens, optional, or lazy references.
