Package: effect
Module: FiberMap

FiberMap.runtime

Capture a Runtime and use it to fork Effect’s, adding the forked fibers to the FiberMap.

Example

import { Context, Effect, FiberMap } from "effect"

interface Users {
  readonly _: unique symbol
}
const Users = Context.GenericTag<Users, {
   getAll: Effect.Effect<Array<unknown>>
}>("Users")

Effect.gen(function*() {
  const map = yield* FiberMap.make<string>()
  const run = yield* FiberMap.runtime(map)<Users>()

  // run some effects and add the fibers to the map
  run("effect-a", Effect.andThen(Users, _ => _.getAll))
  run("effect-b", Effect.andThen(Users, _ => _.getAll))
}).pipe(
  Effect.scoped // The fibers will be interrupted when the scope is closed
)

Signature

declare const runtime: <K, A, E>(self: FiberMap<K, A, E>) => <R = never>() => Effect.Effect<(<XE extends E, XA extends A>(key: K, effect: Effect.Effect<XA, XE, R>, options?: (Runtime.RunForkOptions & { readonly onlyIfMissing?: boolean | undefined; readonly propagateInterruption?: boolean | undefined; }) | undefined) => Fiber.RuntimeFiber<XA, XE>), never, R>
