std.bg
Fire-and-forget background work, with a handle to check on it. See Background tasks for the full guide - this page is the function reference.
import std.bg
t = bg.spawn(fn() expensive())
bg.status(t) # "running" | "completed" | "failed"
bg.result(t) # block for the value; raises if it failed
bg.cancel(t)Functions
| call | effect |
|---|---|
bg.spawn(f) | Start f() in the background |
bg.spawn(f, args) | Start f with a list of arguments |
bg.status(t) | "running", "completed" or "failed" |
bg.result(t) | Block for the value |
bg.cancel(t) | Cooperative cancellation |
bg.after(ms, f) | Run f once after a delay |
bg.every(ms, f) | Run f on an interval until cancelled |
bg.join_all(ts) | Block for all, returning a list of values |
Built on the same machinery as async fn - the handle is the same task value that await accepts.
