Valid input types that can be converted to a Duration.
When to use
Use when an API should accept any value that Effect can convert into a
Duration, including existing durations, millisecond numbers, nanosecond
bigints, high-resolution tuples, duration strings, infinity strings, or
duration objects.
Details
String inputs accept values like "10 seconds", "500 millis",
"Infinity", and "-Infinity". Finite fractional values that are
normalized to nanoseconds are rounded to the nearest nanosecond, with ties
away from zero.

const fromInputUnsafe: (
input: Input
) => Duration
Decodes a Duration.Input into a Duration.
When to use
Use when the input has already been validated or comes from a trusted source
and throwing is acceptable for invalid duration syntax.
Gotchas
If the input is not a valid Duration.Input, it throws an error.
Example (Decoding duration inputs)
import { Duration } from "effect"
const duration1 = Duration.fromInputUnsafe(1000) // 1000 milliseconds
const duration2 = Duration.fromInputUnsafe("5 seconds")
const duration3 = Duration.fromInputUnsafe("Infinity")
const duration4 = Duration.fromInputUnsafe([2, 500_000_000]) // 2 seconds and 500ms
