import { CuidState } from "@typed/id/Cuid";Signatures
export declare class CuidState extends CuidState_base {
static readonly next: Effect.Effect<{
timestamp: number;

}, never, CuidState>;
static readonly Default: Layer.Layer<CuidState, never, never>;
}Why
Counter state and caller-provided envData live in an explicit service so tests and applications choose the sharing boundary instead of relying on hidden globals.
Ownership and lifetime
Each Layer instance owns its mutable counter and captured fingerprint. A new process, worker, or Layer resets that sequence; exact SSR identity must be serialized and reused.
Property: Default
Provides a default CuidState backed by system time and Web Crypto entropy.
Property: Default: Why
The explicit Layer gives production code a standard service while keeping test and environment-specific alternatives replaceable.
Property: Default: Ownership and lifetime
Layer acquisition creates one counter state; the surrounding Layer Scope owns it. Web Crypto must be available in the runtime.
Property: next
Reads one seed from the current CuidState service.
Property: next: Why
The accessor exposes stateful sequencing through Effect’s service channel rather than a module-global counter.
Property: next: Ownership and lifetime
The Effect requires CuidState; its Layer owns the counter for the Layer lifetime.
Examples
import { cuid, CuidState } from "@typed/id/Cuid"
import { Effect } from "effect"
const program = Effect.provide(cuid, CuidState.Default)See Effect services and Layers.
