fn leader

Registers the leader task name (§12.6) and returns at once. On a single node this node is the leader of every task, so body starts in the background scope of the node (no election, the runs leader(name) role clause is not checked, D-2906).

Example:

use std.time { every }
use std.cluster

fn main() io, time {
  cluster.leader("cleanup") {
    every(60s) { print("cleaning") }
  }
}

pub(api) fn leader<effect F>(name: str, body: fn() F)
