(u: unknown): u is Effect<any, any, any>Checks whether a value is an Effect.
Example (Checking whether a value is an Effect)
import { Effect } from "effect"
console.log(Effect.isEffect(Effect.succeed(1))) // true
console.log(Effect.isEffect("hello")) // falseexport const const isEffect: (
u: unknown

isEffect: (u: unknownu: unknown) => u: unknownu is interface Effect<out A, out E = never, out R = never>The Effect interface defines a value that lazily describes a workflow or
job. The workflow requires some context R, and may fail with an error of
type E, or succeed with a value of type A.
When to use
Use when you need to represent a lazy, composable workflow that can require
services, fail with a typed error, or succeed with a typed value.
Details
Effect values model resourceful interaction with the outside world,
including synchronous, asynchronous, concurrent, and parallel interaction.
They use a fiber-based concurrency model, with built-in support for
scheduling, fine-grained interruption, structured concurrency, and high
scalability.
To run an Effect value, you need a Runtime, which is a type that is
capable of executing Effect values.
