Import

import { Guard } from "@typed/guard";

Access Guard.Services through the imported Guard export. Its declaration below describes the member.

Signatures

type Services<T> = [
    T
] extends [
    Guard<infer _I, infer _O, infer _E, infer R>
] ? R : [
    T
] extends [
    AsGuard<infer _I, infer _O, infer _E, infer R>
] ? R : never;

Why

Service extraction makes environment composition visible in combinator signatures.

Ownership and lifetime

This compile-time type acquires no resources; service lifetime is governed by the resulting Effect or Layer.

Examples

import type { Guard } from "@typed/guard"
type Services = Guard.Services<Guard<string, number, never, { readonly Db: unique symbol }>>

Other public imports

These import paths expose the same declaration. Each page retains its own public name and signature.
