fn every

Runs body every d until the task is cancelled (§17.4). Ticks are counted from the start (no drift). When body takes longer than d, .Skip (default) drops the ticks it missed and .CatchUp runs them back to back.

Example:

use std.time { every }

fn main() io, time {
  let (tx, rx) = chan<i64>(cap: 64)
  scope {
    let h = spawn (() => every(10ms) {
      let _ = tx.send(1)
    })
    sleep(75ms)
    h.cancel()
  }
  var ticks = 0
  while rx.tryRecv() != none { ticks += 1 }
  print("{ticks >= 3}")
}

false

pub(api) fn every<effect F>(d: Dur, missed: Missed = .Skip, body: fn() F) time, F
