Type-level representation of
Void
.
Schema for a TypeScript void return value.
When to use
Use when you need to model the return value of a function, RPC, or endpoint
whose result is intentionally ignored.
Details
Runtime parsing accepts any present value and discards it, producing
undefined. The public decoded and encoded TypeScript representation remains
void, so typed construction, decoding, and encoding APIs are still modeled
as void.

Unwraps a Layer from an Effect, flattening the nested structure.
When to use
Use when you have an Effect that produces a Layer and you want to
use that layer directly.
Details
The resulting Layer will have the combined error and dependency types from
both the outer Effect and the inner Layer.
Example (Unwrapping an effectful layer)
import { Context, Effect, Layer } from "effect"
class Database extends Context.Service<Database, {
readonly query: (sql: string) => Effect.Effect<string>
}>()("Database") {}
const layerEffect = Effect.succeed(
Layer.succeed(Database, { query: Effect.fn("Database.query")((sql: string) => Effect.succeed("result")) })
)
const unwrappedLayer = Layer.unwrap(layerEffect)
unwrap(
import EffectEffect.const map: <any, unknown, unknown, any>(self: Effect.Effect<any, unknown, unknown>, f: (a: any) => any) => Effect.Effect<any, unknown, unknown> (+1 overload)Transforms the value inside an effect by applying a function to it.
When to use
Use to transform an effect's success value with a function that returns a
plain value, producing a new effect without changing the original effect's
typed error or context requirements.
Details
map takes a function and applies it to the value contained within an
effect, creating a new effect with the transformed value.
It's important to note that effects are immutable, meaning that the original
effect is not modified. Instead, a new effect is returned with the updated
value.
Example (Choosing map syntax variants)
import { Effect, pipe } from "effect"
const myEffect = Effect.succeed(1)
const transformation = (n: number) => n + 1
const mappedWithPipe = pipe(myEffect, Effect.map(transformation))
const mappedWithDataFirst = Effect.map(myEffect, transformation)
const mappedWithMethod = myEffect.pipe(Effect.map(transformation))
Example (Adding a service charge)
import { Effect, pipe } from "effect"
const addServiceCharge = (amount: number) => amount + 1
const fetchTransactionAmount = Effect.promise(() => Promise.resolve(100))
const finalAmount = pipe(
fetchTransactionAmount,
Effect.map(addServiceCharge)
)
Effect.runPromise(finalAmount).then(console.log)
// Output: 101

Build the live
QueueEngine
handle behind tag and map it onto the toolkit service
impl — the single adapter shared by the local layer (
layer
) and the served
forms (
serve
/
serveRemote
). The worker R is captured at build time and
provided to each method, so the impl requires nothing beyond the scope; the engine queue
name defaults to the tag id (telemetry attribution) unless config.name overrides.
The queue spec has no
Hyperlink.local
members, so the resulting impl satisfies both
ImplOf (for Hyperlink.layer / Hyperlink.serve) and ServeImplOf (for Hyperlink.serveRemote).
