Why do Structs in tokio::spawn blocks need to be Send even when running in single thread mode?
⚓ Rust 📅 2025-11-12 👤 surdeus 👁️ 5I am running my async program in single threaded mode:
#[tokio::main(flavor = "current_thread")]
But when doing,
let handle = tokio::spawn(async move {
worker.run(controller);
});
The rust analyzer gives me an error "captured value is not Send".
While I understand the issue in multi-threaded runtime mode, why should this be the case in single-threaded mode?
