Effect.Effect<number, never, never>Generates a random integer between Number.MIN_SAFE_INTEGER (inclusive)
and Number.MAX_SAFE_INTEGER (inclusive).
When to use
Use to generate a pseudo-random safe integer across the full safe-integer range.
Example (Generating a random integer)
import { Effect, Random } from "effect"
const program = Effect.gen(function*() {
const randomInt = yield* Random.nextInt
console.log("Random integer:", randomInt)
})Random Number Generators
