fn iterate

Infinite sequence seed, step(seed), step(step(seed)), ….

Example:

oxl✓ checked in CI

fn main() io {
  print("{iterate(1, x => x * 2).take(5).collect()}")
}

Output

[1, 2, 4, 8, 16]

pub(api) fn iterate<T, effect F>(seed: T, step: fn(T) -> T F escaping) -> iter<T>  F

Complexity. O(1) to build; each pull applies `step` once.

Since. 1.0.0-beta

Parameters

Name	Type
`seed`	`T`
`step`	`fn(T) -> T F escaping`

iter<T> F
