zbackoff implements jittered backoff. Useful when retrying operations that can potentially fail (i.e. network calls). The implementation is based on this article from the AWS Architecture Blog.

You can use it like so:

const std = @import("std");
const zbackoff = @import("zbackoff");

fn funcThatFails() !u64 {
    _ = try std.time.Instant.now();
    std.debug.print("funcThatFails()\n", .{});
    return error.UnwantedResult1;
}

pub fn main() void {
    var bo = zbackoff.Backoff{};
    for (0..3) |_| {
        const result = funcThatFails() catch {
            std.time.sleep(bo.pause());
            continue;
        };
        _ = result;
        break;
    }
}
