Function fromInputUnsafe

repos/effect/packages/effect/src/Duration.ts:228–307

(input: Input)

 * If the input is not a valid `Duration.Input`, it throws an error.
 *
 * **Example** (Decoding duration inputs)
 *
 * ```ts import.meta.vitest
 * import { Duration } from "effect"
 *
 * Duration.fromInputUnsafe(1000) // => Duration.millis(1000)
 * Duration.fromInputUnsafe("5 seconds") // => Duration.seconds(5)
 * Duration.fromInputUnsafe("Infinity") // => Duration.infinity
 * Duration.fromInputUnsafe([2, 500_000_000]) // => Duration.nanos(2_500_000_000n)
 * ```
