Struct Id

An opaque ID that uniquely identifies a runtime relative to all other currently running runtimes.

Notes

• Runtime IDs are unique relative to other currently running runtimes. When a runtime completes, the same ID may be used for another runtime.
• Runtime IDs are not sequential, and do not indicate the order in which runtimes are started or any other data.
• The runtime ID of the currently running task can be obtained from the Handle.

Examples

use tokio::runtime::Handle;

#[tokio::main(flavor = "multi_thread", worker_threads = 4)]
async fn main() {
  println!("Current runtime id: {}", Handle::current().id());
}
